Description

  The present invention relates to a method for identifying a eukaryotic species. More specifically, the present invention relates to a eukaryotic organism characterized in that analysis is performed using as an index the amino acid sequence encoded by the base sequence of a specific DNA region of RNA polymerase I largest subunit gene (sometimes abbreviated as PolA1 gene). The present invention relates to a species identification method. More specifically, the present invention uses DNA obtained from a sample as a template, and DNA encoding an amino acid sequence sandwiched between two regions that are conserved in the process of evolution existing in the C-terminal region of RNA polymerase I largest subunit. The region is amplified using a primer prepared based on the base sequence encoding each of the two regions, the amino acid sequence encoded by the base sequence of the generated amplification product is determined, and the determined amino acid sequence is The present invention relates to a method for identifying a eukaryotic species, characterized by identifying a eukaryotic species as a sample by comparing with the amino acid sequence of a eukaryotic PolA1 gene registered in a computer database.

  There are 3 to 10 million species listed on the earth, and it is estimated that there are actually more than 10 times this species. Scientific names of organism species have been described and systematized in two nomenclatures (genus name and species name) based on morphological characteristics established by Carl von Linne. About 250 years later, even though the study of genetics and molecular biology has advanced significantly, it has become possible to analyze the relationship between species in detail, but a new organism that replaces Linne's two nomenclature The species classification method has not been established yet.

  According to Linne's two nomenclature, species of organisms are identified based on differences in external morphology, so it is often impossible to identify species unless they are specialists of each organism. In addition, the classification standards of species differ among taxonologists. Furthermore, since the number of researchers specializing in morphological taxonomy is currently declining significantly, it is expected that a situation where species cannot be identified based on morphology in the near future can occur sufficiently.

  In recent years, with the progress of DNA analysis technology, researches to characterize organism species and strains by DNA base sequences have been actively conducted (Non-patent Document 1). The present inventors have found that the region between rpl16 and rpl14 genes on chloroplast DNA corresponds well with the plant affinity, and the sequence of this region is referred to as a plastid subtype identity (PSID) sequence. (Non-patent document 2). Although this PSID sequence is as short as about 100 to 300 bases, it is effective for identifying plant genera and species (Non-Patent Document 3, Non-Patent Document 4, Non-Patent Document 5, Non-Patent Document 6, Non-Patent Literature 7 and Non-patent literature 8). Recently, Herbert et al. Proposed an attempt to distinguish species of all organisms (DNAbarcoding) using the nucleotide sequence of mitochondrial cytochrome c oxidase I (CO1) gene (Non-Patent Document 9 and Non-patent document 10). DNA barcoding using CO1 gene includes insects (Non-Patent Document 11), birds (Non-Patent Document 12), fish (Non-Patent Document 13), red algae (Non-Patent Document 14), fungi (Non-Patent Document 15), etc. There are reports in many organisms, and there is also an evaluation with the renaissance in biotaxonomy (Non-patent Document 16).

  On the other hand, since the evolution rate of the CO1 gene is slow in plants, DNA barcoding using a gene sequence of chloroplast DNA has been proposed (Non-patent Documents 17 and 18). In addition, since mitochondrial and chloroplast DNA is transmitted by cytoplasmic inheritance, it is impossible to distinguish interspecific hybrids and diploid species that are abundant in plants. Furthermore, since the transfer of mitochondrial DNA fragments to the nuclear genome has been reported in animals (Non-patent document 19), plants (Non-patent document 20), etc., there are many critical opinions on DNA barcoding using the CO1 gene ( Non-patent document 21 and Non-patent document 22). For this reason, DNA barcoding using a plurality of nuclear genes has also been studied (Non-patent Document 23 and Non-Patent Document 24).

  Ribosomal RNA (rRNA) genes are known as DNA base sequences effective for classifying species in various organisms (Non-patent Documents 25 and 26). It is known that the base sequences of 16S and 23S rRNA genes are effective for identifying prokaryotic genera and species (Non-patent Document 27). On the other hand, in eukaryotes, the homology of the rRNA gene is high, so the nucleotide sequence of the ITS1 (internal transcribed spacer 1) region between the 18S rRNA gene and the 5.8S rRNA gene and the ITS2 region between the 5.8S rRNA and 28S rRNA genes. Has been reported to be effective for the identification of genera and species (Non-patent Document 28). In contrast, eukaryotic rRNA genes are not suitable for distinguishing genera and species because hundreds of copies are present in the nuclear genome in tandem and interspersed and show intraspecific variation. There is also a report (Non-patent document 29).

  Therefore, research on unique genes contained in one to several copies in the nuclear genome is also being conducted. For example, glycerol-3-phosphate acyltransferase (Glycerol-3-phosphateacyltransferase, Non-Patent Document 30), alcohol dehydrogenase (Alcohol dehydrogenase, Non-Patent Document 31), glutamine synthetase (Glutamine synthetase, Non-Patent Document 32) Since the housekeeping gene having a unique function is contained in all living organisms, it is effective for species identification and estimation of the affinity. However, since mutation occurs only in a region that does not affect each enzyme activity, there is a known case where distant relations do not correspond to similar relations (Non-patent Document 33).

  In general, in order to elucidate the speciation of an organism, it is common knowledge to analyze a large number of DNA markers contained in the genome and create a molecular phylogenetic tree. Therefore, the idea of Phylocode, which tries to use this molecular phylogenetic tree as a species name, has been proposed (Non-Patent Document 34 and Non-Patent Document 35), but many DNA markers are analyzed for all species and lines. To do this, a large amount of money is required. In addition, it seems difficult to analyze using many common DNA markers in all eukaryotes. Furthermore, Phlylocode is also a problem that it is a completely independent concept from the classification system and knowledge accumulation by the conventional two nomenclature (Non-patent Document 36).

  Species of organisms are classified using two nomenclatures organized by Linne based on differences in morphological characteristics. With the progress of molecular biology, gene and genome information of many biological species has been obtained, but it has always been collated with the classification results by conventional forms. If the species of an organism can be specified using an amino acid sequence, it will be possible to greatly contribute to identification, identification, classification, and the like.

  An object of the present invention is to provide a method for identifying a species useful for identification, identification, classification, and the like of an organism.

  In general, speciation of organisms is thought to be caused by the nuclear genome rather than the cytoplasmic genome, so in order to elucidate the speciation, the nucleotide sequence of a gene contained in only one copy in the haploid genome It is considered better to investigate. Moreover, in order to specify a species, it is desirable that it is a gene contained in the nucleus of all eukaryotes.

  The present inventor has established a eukaryote in the C-terminal region of RNA polymerase I largest subunit, which is the largest subunit of RNA polymerase I complex involved in the synthesis of ribosomal RNA (rRNA) essential for maintaining life. We found that there is an amino acid sequence that shows a specific mutation in this species, and focused on this. This amino acid sequence consists of about 370 amino acid residues sandwiched between two highly conserved regions and is encoded by a base sequence of about 1.1 kb. Since this amino acid sequence and the base sequence encoding the amino acid sequence can be determined one by one per haploid genome, it can be applied not only to diploids but also to hybrids and polydiploid species. It can be used as an index to identify nuclear species. The present invention has been achieved based on this finding.

That is, the present invention relates to a method for identifying a eukaryotic species comprising the following steps:
(I) a step of preparing DNA from a sample;

(Iii) determining the base sequence of the obtained amplification product, and decoding the amino acid sequence encoded by the base sequence; and (iv) converting the decoded amino acid sequence into a eukaryotic organism registered in a computer database. A step of comparing with the amino acid sequence of the PolA1 gene.

  The present invention is also the above-described method for identifying a eukaryotic species, wherein one of the two regions that are conserved in the process of evolution existing in the C-terminal region of the protein encoded by the PolA1 gene is A region represented by the 1175th to 1194th amino acid sequence (SEQ ID NO: 1) of the protein, and the other region represented by the 1581st to 1596th amino acid sequence of the protein (SEQ ID NO: 2), wherein the position is associated with a protein encoded by the base sequence of the accession number NM_115626 of the PolA1 gene of Arabidopsis thaliana. About.

  INDUSTRIAL APPLICABILITY According to the present invention, a method for identifying a eukaryotic species can be provided which comprises analyzing an amino acid sequence encoded by the base sequence of a specific DNA region of RNA polymerase I largest subunit gene as an index. The amino acid sequence encoded by the base sequence of the specific DNA region analyzed in the species identification method according to the present invention has two conservative properties in the process of evolution existing in the C-terminal region of the RNA polymerase I largest subunit. Amino acid sequence between regions. Furthermore, the present invention can provide a primer useful for a method for identifying a eukaryotic species.

  The species identification method according to the present invention is useful for organism identification, identification, classification, and the like.

  RNA polymerase I The amino acid sequence between two highly conserved regions existing in the C-terminal region of the largest subunit and the base sequence that encodes the amino acid sequence are not merely a list of amino acids and base sequences, but are related to the strain. In addition to being effective in determining the description of new species and variety patents, etc., management, identification, and identification of resource organisms, rare organisms, disease organisms, food organisms, raw organisms, experimental organisms, etc. It can be applied to diagnosis and investigation. In particular, it is also useful as a reference to prevent biological strain differences at Genebank, which has recently become a problem.

  The present invention relates to a method for identifying eukaryotic species. In this method, species identification is carried out using as an index the amino acid sequence showing a mutation specific to a eukaryotic species present in the C-terminal region of the protein encoded by the eukaryotic RNA polymerase I largest subunit gene. It is characterized by. In the present specification, a region encoding this amino acid sequence in the RNA polymerase I largest subunit gene is referred to as a specific DNA region of the RNA polymerase I largest subunit gene.

  “Identification of eukaryotic species” includes both identifying eukaryotic species of different species and identifying eukaryotic subspecies of the same species. “Eukaryote” refers to an organism having a structure called a cell nucleus in cells constituting the body, and includes animals, plants, fungi, protists, and the like. “Species” is the basic unit of biological classification and refers to the category immediately below the genus or subgenus. In general, it can be defined as a population of organisms that can be mated and as a result can leave offspring. “Subspecies” refers to subdivisions of species in a biological taxonomy. In the case of plants, subspecies and variety are used interchangeably.

The eukaryotic species identification method according to the present invention comprises the following steps:
(I) a step of preparing DNA from a sample;
(Ii) a process of amplifying a specific DNA region of RNA polymerase I largest subunit gene (PolA1 gene) using the DNA as a template, wherein the specific DNA region is present in the C-terminal region of the protein encoded by the gene A DNA region that encodes an amino acid sequence sandwiched between two regions that are conserved in the course of evolution.
(Iii) determining the base sequence of the obtained amplification product, and decoding the amino acid sequence encoded by the base sequence; and (iv) converting the decoded amino acid sequence into a eukaryotic organism registered in a computer database. A step of comparing with the amino acid sequence of the PolA1 gene.

  Any sample can be used as long as it is a sample derived from a eukaryote and contains a nucleic acid. Preparation of DNA from a sample can be performed using a known DNA preparation method. For example, the preparation of total genomic DNA is performed by the CTAB (Cetyltrimethil ammmonium bromide) method (Doyle, JJ et al., “A rapid DNA isolation procedure for small quantities of fresh leaftissue”, Phytochemical Bulletin, 1987, Vol. 19, p.11-15) and its modification method. The cDNA can be prepared, for example, by the method of Gubler and Hoffman (Gubler, U. et al., “A simple and very efficient method for generating cDNA libraries”, Gene, 1983, Vol. 25, p. .263-269).

  “RNA polymerase largest subunit 1 (sometimes abbreviated as POLA1)” is the largest subunit of the RNA polymerase I complex involved in the synthesis of ribosomal RNA (rRNA) that is essential for maintaining life. The gene encoding POLA1 is referred to as RNA polymerase I largest subunit gene (hereinafter sometimes abbreviated as PolA1 gene).

  The “specific DNA region of the PolA1 gene” is a region encoding an amino acid sequence showing a mutation specific to a eukaryotic species present in the C-terminal region of POLA1.

  The specific DNA region of the PolA1 gene is referred to herein as Ntag. A DNA region encoding an amino acid sequence sandwiched between two regions that are conserved in the process of evolution existing in the C-terminal region of the protein encoded by the PolA1 gene, and consists of about 1.1 kb.

  A region present in the C-terminal region of POLA1 encoded by Ntag is referred to as Ptag. The Ptag sequence is an amino acid sequence sandwiched between two regions that are conserved in the process of evolution existing in the C-terminal region of POLA1, and consists of 300 to 500 amino acid residues. The Ptag sequence is an amino acid sequence that shows mutations specific to eukaryotic species.

  Of the two regions that are conserved during the evolution process across the Ptag sequence, the region adjacent to the N-terminal side of the Ptag sequence is called PBL (Protein border sequence of left), and the region adjacent to the C-terminal side of the Ptag sequence Is called PBR (Protein border sequence of right). In addition, the DNA regions of the PolA1 gene encoding PBL and PBR, respectively, are referred to as NBL and NBR. NBL and NBR sequences corresponding to PBL and PBR sequences, respectively, are also well conserved during evolution.

  Two regions that are conserved in the process of evolution sandwiching the Ptag sequence, for example, PBL is a region represented by the amino acid sequence of the 1175th to 1194th amino acids (SEQ ID NO: 1) of POLA1, and PBR is the protein This region is represented by the 1581st to 1596th amino acid sequence (SEQ ID NO: 2) of No. 1, where this position is encoded by the nucleotide sequence of the accession number NM_115626 of the PolA1 gene of Arabidopsis thaliana. It is associated with proteins.

  PBL and PBR in each eukaryotic POLA1 can be identified, for example, based on homology with the PBL and PBR of the protein encoded by the Arabidopsis thaliana PolA1 gene (SEQ ID NO: 1 and SEQ ID NO: 2, respectively) . A region consisting of an amino acid sequence having at least 40% or more, preferably 50% or more, more preferably 60% or more homology with the amino acid sequence shown in SEQ ID NO: 1 can be identified as PBL. A region consisting of an amino acid sequence having at least 40% or more, more preferably 50% or more, more preferably 60% or more, even more preferably 70% or more homology with the amino acid sequence shown in SEQ ID NO: 2 is referred to as PBR. Can be identified. Furthermore, since the number of amino acids of Ptag, which is an amino acid sequence sandwiched between PBL and PBR, is 300 to 500 residues, in addition to the above homology, between one region and the other region of the two regions When the number of amino acids between them is 300 residues or more, preferably 300 to 500 residues, the two regions can be identified as PBL and PBR. For example, human PBL and PBR have 95% homology with the amino acid sequence set forth in SEQ ID NO: 1 and 69% with the amino acid sequence set forth in SEQ ID NO: 2, respectively. Giardia PBL and PBR have 70% homology with the amino acid sequence set forth in SEQ ID NO: 1 and 63% with the amino acid sequence set forth in SEQ ID NO: 2, respectively. Malaria protozoa (Malaria) PBL and PBR have 50% homology with the amino acid sequence set forth in SEQ ID NO: 1 and 70% and with the amino acid sequence set forth in SEQ ID NO: 2, respectively. Theileria PBL and PBR have 85% homology with the amino acid sequence set forth in SEQ ID NO: 1 and 69% homology with the amino acid sequence set forth in SEQ ID NO: 2, respectively. Naegleria PBL and PBR have a homology of 65% with the amino acid sequence set forth in SEQ ID NO: 1 and 56% with the amino acid sequence set forth in SEQ ID NO: 2, respectively.

  Ptag and Ntag sequences can be determined one by one per haploid genome, so they can be applied not only to diploid but also to hybrid and polydiploid species, so all eukaryotic species are identified Can be used as an indicator for “Haploid”, also referred to as haploid or monophasic, means a cell or individual having only half the chromosome set. The gametes produced by maturation are only haploid with only one set of genomic chromosomes. “Hybrid” refers to an organism born by mating / crossing between individuals of different strains in genetics. “Diploid” refers to a cell or individual having a chromosome number twice that of the basic number. When the genome is clear, it means an individual with two identical genomes. “Amphidiploid” refers to an allogeneic tetraploid with two different genomes.

  Determination of the Ptag sequence of each eukaryote can be performed by decoding the Ntag sequence encoding the Ptag sequence in the genomic DNA or cDNA base sequence. The Ntag sequence can be decoded, for example, by amplifying Ntag and sequencing it.

  Amplification of Ntag can be performed using a known technique capable of amplifying a gene fragment. For example, Ntag amplification can be easily performed by a polymerase chain reaction (abbreviated as PCR) using a primer capable of amplifying the specific DNA region. . PCR is a reaction that specifically amplifies a DNA fragment sandwiched between a set of primers by executing a DNA polymerase reaction continuously and in a chain.

  Since the amino acid sequence encoded by the Ntag sequence is an amino acid sequence sandwiched between two regions that are conserved during the evolution process existing in the C-terminal region of the protein encoded by the PolA1 gene, for example, the two Using a primer set consisting of a primer designed based on a base sequence encoding one region of a conservative region and a primer designed based on a base sequence encoding the other region, the two conservation properties The Ntag sequence between the regions having can be amplified.

  That is, Ntag can be amplified by PCR using a primer set prepared based on the NBL sequence and NBR sequence. As mentioned above, both NBL and NBR sequences are well conserved during the evolution process as PBL and PBR sequences, so primers that are useful in closely related species are designed based on NBL and NBR sequences. It is possible to perform PCR amplification and sequencing of Ntag sequences.

  The base sequence of the amplification product can be determined using a known genetic engineering technique. For example, it can be simply carried out using a commercially available DNA sequencer.

  In fungi and nematodes, no intron is found inside the Ntag sequence, so that DNA fragments containing the Ntag sequence can be amplified using not only cDNA but also genomic DNA as a template, and analysis of the Ntag sequence can be easily performed. On the other hand, in eukaryotes such as animals, plants and insects, the Ntag sequence is separated by a plurality of introns. Depending on the species, a transposon or the like may be inserted into the intron and the intron may be extremely long. Therefore, it may be difficult to analyze the Ntag sequence by amplifying a DNA fragment containing the Ntag sequence using genomic DNA as a template. In such a case, analysis of the Ntag sequence can be carried out by amplifying Ntag by PCR using cDNA as a template and decoding the base sequence using direct sequencing.

  The amino acid sequence encoded by the amplified DNA fragment, that is, the Ptag sequence can be easily determined from the base sequence of the obtained amplification product.

  The amino acid sequence encoded by the amplified DNA fragment is compared with the amino acid sequence of the known eukaryotic POLA1. Comparison of amino acid sequences can be performed using a computer database. NCBI's pblastn web server (Altschul, SF et al., “Basic local alignment search tool”, Journal of Molecular Biology, 1990, Vol. 215, p. 403-410 ), Clustal W (Thompson, JD) of DDBJ of the National Institute of Genetics, “CLUSTAL W: improving the sensitivity of progressive multiple sequence alignment through sequence weighting, position-specific gap penalties and weight matrix choice”, Nucleic Acids Research (Nucleic Acids Research), 1994, Vol. 22, No. 22, p. 4673-4680).

  If POLA1 containing the amino acid sequence encoded by the amplified DNA fragment is found in a protein database or DNA database by comparing the amino acid sequences, the eukaryotic species or subspecies having the POLA1 is amplified. Can be determined to be a eukaryotic species or subspecies from which

  For example, in the method for identifying a eukaryotic species according to the present invention, when determining whether a sample is a eukaryote of a specific species or subspecies, the Ntag sequence of the specific species or subspecies can be amplified. Using a pair of primers, an amplification reaction is performed using the nucleic acid extracted from the sample as a template. The base sequence of the obtained DNA fragment is determined, and the amino acid sequence encoded by the DNA fragment is compared with the amino acid sequence of POLA1 of the specific species or subspecies. If the amino acid sequence encoded by the DNA fragment matches the amino acid sequence of POLA1 of the specific species or subspecies, it can be determined that the sample is a eukaryote of the specific species or subspecies.

  Further, for example, in the method for identifying a eukaryotic species according to the present invention, when discriminating a plant species or subspecies as a sample, the sample is used by using one or more primers capable of amplifying a plant Ntag sequence. An amplification reaction is performed using the nucleic acid extracted from the template as a template. The base sequence of the obtained DNA fragment is determined, and the amino acid sequence encoded by the DNA fragment is compared with the amino acid sequence of plant POLA1 registered in a protein database or DNA database. If a species or subspecies having POLA1 containing an amino acid sequence that matches the amino acid sequence encoded by the DNA fragment is found in the searched database, the sample can be determined to be a plant of the special species or subspecies.

  On the other hand, if POLA1 containing the amino acid sequence encoded by the amplified DNA fragment is not found in the protein database or DNA database, the eukaryotic species or subspecies from which the amplified DNA fragment was derived may be a new species It can be determined that there is sex. In such a case, by performing molecular phylogenetic analysis on the amino acid sequence encoded by the amplified DNA fragment, the eukaryotic species or subspecies from which the amplified DNA fragment was derived is any species or subspecies. Can be predicted. "Molecular phylogenetic analysis" is a method to estimate the path (system) in which an organism has evolved (by creating a phylogenetic tree) by comparing the amino acid sequence of the protein of the organism and the base sequence of the gene. . Molecular phylogenetic analysis is, for example, MEGA4 (Tamura, K. et al., “MEGA4: Molecular Evolutionary Genetics Analysis MEGA Software Version 4.0”, Molecular Biology and Evolution, 2007, Vol. 24, p.1596-1599).

  Thus, in addition to the steps (i) to (iv) above, the method for identifying a eukaryotic species according to the present invention further comprises (v) a step of performing a molecular phylogenetic analysis based on the decoded amino acid sequence. Can be included.

  In the method according to the present invention, primer sets used for amplification of Ntag encoding a Ptag sequence are exemplified below. This method can be performed using any one of these primer sets, or two or more sets.

  Specific examples of primers used for amplification of Ntag encoding a Ptag sequence include the primers shown in Table 1. The Ntag sequences of the species shown in Table 1 are encoded over the 19th, 20th and 21st exons, and NBL and NBR sandwiching the Ntag sequence are the 19th and 21st exons, respectively. Exists. The primer set consisting of 19ex5P and 21ex3P shown in Table 1 can be used as a primer for amplification of the Ntag of the corresponding species shown in Table 1. Note that 20ex5Pi and 20ex3Pi in Table 1 are sequencing primers used for sequencing amplification products obtained using the amplification primers shown in Table 1.

  EXAMPLES Hereinafter, although an Example is shown and this invention is demonstrated more concretely, this invention is not limited at all by the Example shown below.

(1) Examination of homology of the largest subunits of three types of RNA polymerases in plants Each of the three types of RNA polymerase complexes in Arabidopsis: RNA polymerase I complex, RNA polymerase II complex, and RNA polymerase III complex The homology of the largest subunits POLA1, POLB1, and POLC1 with the β ′ largest subunit of the E. coli RNA polymerase complex was compared.

  As a result, although they were generally similar to each other, a specific CTR (C-terminal repeat) sequence was contained at the C-terminus of the POLB1 subunit. In addition, in the POLA1 subunit, about 180 amino acid sequences were inserted in the N-terminal and C-terminal regions, respectively, compared to the other two subunits (FIG. 1).

(2) Comparison of plant POLA1 subunits In order to compare the homology of plant POLA1 subunits, the rice genome database was searched to identify the PolA1 gene. The rice PolA1 gene is approximately 15 kb long and is divided into 21 exons and encodes a large protein of 1673 amino acid residues (approximately 188 kDa).

  When comparing the amino acid sequences encoded by each exon of the PolA1 gene between rice and Arabidopsis, as shown in Fig. 2, 15 out of 21 exons showed high homology of 40% or more. However, amino acid sequence homology was found to be significantly lower in exons 4-5 and 20 corresponding to the two inserted sequences of the N-terminal and C-terminal regions specific for the POLA1 subunit described above. It was. This 20th exon was the longest exon in the plant PolA1 gene.

(3) Comparison of plant PolA1 gene exon 20 For the rice plants Makomo, barley, barley, single wheat, petunia and cherry, a DNA fragment containing the 20th exon of the PolA1 gene was amplified by PCR, and the direct sequence was used. The nucleotide sequence was analyzed by the method. Primers used for amplification and sequencing of DNA fragments were designed based on the nucleotide sequences of rice, wheat, tomato, almond EST (expression sequence tag) (Table 1).

  In addition, DNA sequences were searched to collect base sequences of exon 20 of plant PolA1 gene. When the base sequences of the 13th exon thus obtained were converted to amino acid sequences and molecular phylogenetic analysis was performed using MEGA4, it was revealed that the mutations closely matched the plant affinity (Fig. 3). ).

(4) Ptag sequence setting In order to compare the amino acid sequence of the C-terminal region of all eukaryotic POLA1 proteins, the base sequence of the whole genome from five taxonomic groups of fungi, nematodes, insects, animals and plants Search for PolA1 gene sequences of 8 species that have been decoded (Arabidopsis thaliana, Oryza sativa, Homo sapiens, Mus musculus, Xenopus laevis, Danio rerio, Caenorhabditis elegans, Saccharomyces cerevisiae) and are highly conserved among POLA1 proteins PBR and PBL sequences were identified.

  The identified PBR and PBL sequences were about 20 and 16 residues, respectively (Figure 4). The amino acid sequence between the two conserved sequences was set as a Ptag sequence for characterizing the eukaryotic haploid genome. When these 8 Ptag sequences were compared, no homology was found between the 5 taxa.

(5) Structure of the eukaryotic PolA1 gene When comparing the structure of the PolA1 gene of representative species belonging to different eukaryotic taxonomic groups, it was found that the exon structure is greatly different. FIG. 5 schematically shows the structure of fungal, nematode, insect and animal genes in the region corresponding to exons 19 to 21 of the plant PolA1 gene. Within this region, there are 2 introns in plants, 3 in nematodes, 4 in insects, and 8 in animals, but no introns were found in fungi and protists. In addition, exon length and intron insertion position in each taxon were well preserved, but intron length varied greatly depending on species and strains due to insertion and deletion of transposon and the like.

(6) Analysis of Ntag sequence and Ptag sequence The Ntag sequence of each organism was collected by searching with a tblastn server using a Ptag sequence as a query in a DNA database such as NCBI. The collected base sequences were converted to amino acid sequences to identify PBR and PBL sequences. NBR and NBL sequences corresponding to the identified PBR and PBL sequences were analyzed (FIG. 6), and the base sequences between the two were compared with the EST database. However, in most species, EST clones containing full-length Ntag sequences could not be detected, so Ntag and Ptag sequences were determined using partial EST information. In vertebrates and the like, the Ptag sequence was analyzed using the base sequence attached with the annotation of the PolA1 gene.

  So far, a total of 120 Ptag sequences have been determined, including 57 fungi, 18 insects, 2 nematodes, 14 animals, 15 plants, and 14 protists (other eukaryotes). The average length of the sequence was 366 residues. The shortest Ptag sequence had 301 residues of the microsporidia Encephalitozoon cuniculi, and the longest was significantly different from the 457 residues of Piroplasma parasite Babesia bovis (Tables 3-1 to 3- 7). The Ptag sequence contained two types of acidic amino acids (glutamic acid and aspartic acid) in a total of 14 to 25% (Tables 3-1 to 3-7). Since the content of the two acidic amino acids in a normal protein is about 9%, the content of acidic amino acids in this Ptag sequence appears to be abnormally high. Although the function of this Ptag sequence is not yet understood, it is possible that it is involved in binding to the DNA strand because of its high acidic amino acid content. Further, the DNA fragment encoding the full-length Ptag sequence could not be cloned using an E. coli plasmid. Although it is not known whether this is associated with a high content of acidic amino acids, it is thought to be consistent with the fact that EST clones containing the full-length Ntag sequence cannot be detected from the DNA database. Furthermore, since the Ptag sequence contains many unique amino acid sequences that are not found in ordinary proteins, it is considered that synthetic peptide antibodies can be produced and applied to species determination.

(7) Molecular phylogenetic tree created from eukaryotic Ptag sequences
Most of the Ptag sequences collected from DNA databases are of fungi. This is because the Ntag region of the fungus does not contain an intron, so the Ptag sequence could be determined directly from the genomic DNA base sequence. In order to accurately align various Ptag sequences, common (eg, rice) PBR and PBL sequences were added to both ends of the Ptag sequence. The collected 120 Ptag sequence data were aligned by Clustal W, input to MEGA4 software, and a molecular phylogenetic tree was created using the neighborhood distance coupling method (FIGS. 7-1 and 7-2).

  In the obtained molecular phylogenetic tree, fungi, animals (nematodes, insects, vertebrates) and plants formed three large groups each. Species belonging to the fungus Ascomycota are divided into three main groups: Aspergillus group, such as filamentous fungi group, Shizosaccharomyces group, and Saccharomycesis unicellular group. Divided. The Aspergillus genus and Neosartorya (Aspergillus tereomorph) genus formed one clade, and the various fungal groups were in good agreement with the conventional classification. On the other hand, in the yeast genus group, there were some differences from the conventional classification system, including two species of the genus Saccharomyces and one species of the genus Candida included in different clades. The Basidiomycota Laccaria, Malassezia, Cryptococcus, and Ustilago4 genera formed a clade. In addition, the genus Batrachochytrium of Chitridiomycota and the Rhizopus genus of Zygomycota belonged to the same clade as Shizosaccharomyces genus, but this seems to be due to the fact that the test strain was one species at a time. It is.

  Monosiga brevicollis, the origin of metacellularization of metazoans, diverged from a common ancestor of fungi, animals and plants. The diatom (Thalassiosira) was contained in the same clade as the three genus Phytophthora. The nematodes belonging to the animal kingdom (Nematoda), insects (Insecta) and vertebrates (Vertebrata) formed a large clade. The sea anemone (Nematostella vectensis) Sea urchins (Strongylocentrotuspurpuratus) were located between nematodes and vertebrates. In insects, 12 species of the genus Drosophila were included in the same group, which was consistent with the conventional classification system. In vertebrates, the positions of amphibians and birds were reversed from the conventional classification system, but various other relationships were consistent with the conventional theory. Twelve terrestrial plants formed the same clade with the unicellular green algae Chlamydomonas sp. (C. reinhardtii) and two Ostreococcus sp. (O. lucimarinus, O. tauri). Nine dicotyledons and three monocotyledons were clearly branched.

  Two protozoan Entamoeba genera (E. histolytica, E.dispar), slime mold (Dictyosterium discoidem), ciliate Paramecium tetraurelia and GiardiaLamblia form a group did. Three species of Piroplasma parasites (Theileria annulata, T. parva, Babesia bovis) and microsporidia (Encephalitozoonconiculi) belonged to the fastest branched clade.

(8) Comparison of Ptag and Ntag sequences of strains classified into the same species Although there are not many examples of Ptag sequences determined so far in strains classified into the same species, two species of the fungus Coccidioides genus In C. immitis and C. poradasii, 3 and 4 Ptag sequences could be determined, respectively (Table 4). Two residue substitutions were observed between the two Ptag sequences, but strains belonging to the same species each showed the same Ptag sequence. On the other hand, in the Ntag sequence, substitution of 8 bases was observed between both species, and in 1 strain (2133) of C. poradasii, 2 substitutions with other 3 strains of the same species were observed. In Candida albicans, two Ptag and Ntag sequences could be determined. There were 4 base substitutions in the Ntag sequence between the two lines, but the Ptag sequence was the same. In two strains of Cryptococcus neoformans, both Ptag and Ntag sequences were the same.

  In Table 4, the numerical values shown in the items of the degree of change of Ptag and the degree of change of Ntag indicate the length of each amino acid sequence and base sequence for each line described in the top row, and for other lines Indicates the number of amino acids and nucleotides different from those of the outer strain.

  Next, the Ntag and Ptag sequences of each of the three lines classified into two ecotypes (Indian and Japanese) of cultivated rice (Oryza sativa) were analyzed. As a result, although no mutation was observed in each ecotype, substitution of 2 to 4 bases in the Ntag sequence and 1 residue in the Ptag sequence was observed between the Indian and Japanese types (Table 4).

(9) Identification of subspecies of cultivated rice using Ptag sequence and Ntag sequence as indicators. The Indian type and Japanese type of cultivated rice (Oryza sativa) were used as samples, and they were identified. Genomic DNA was extracted from each sample according to the DNA extraction method described below. As a primer for amplifying rice Ntag, an oligonucleotide represented by the nucleotide sequence set forth in SEQ ID NO: 5 and an oligonucleotide represented by the nucleotide sequence set forth in SEQ ID NO: 8 (FIG. 9) were used. Rice Ntag was amplified by PCR using the genomic DNA as a template and the above-mentioned pair of primers. The amplified DNA fragment was purified and the nucleotide sequence was decoded. The base sequence was decoded using the Big Dye Terminator Cycle Sequencing Kit (AppliedBiosystems) and sequence primer (SEQ ID NO: 6 and SEQ ID NO: 7), and then ABI3100 sequencer (Applied Biosystems). did.

  The analyzed Ntag sequence was searched using the amino acid sequence of POLA1 protein as a query using NCBI's pblastn web server. As a result, the amino acid sequence encoded by the base sequence of the DNA fragment amplified as described above using Indian rice as a sample matched the amino acid sequence of Indian rice registered in the computer database. In addition, the amino acid sequence encoded by the base sequence of the DNA fragment amplified as described above using Japanese rice as a sample matched the amino acid sequence of Japanese rice registered in the computer database. Thus, using the amino acid sequence encoded by Ntag as an index, we were able to distinguish between Indian and Japanese subspecies of rice.

(10) Discrimination of phytopathogenic fungus Fusarium using Ptag and Ntag sequences as indicators. Among the Fusarium oxysporum species, Race1-2 and Race4 that infect bananas were identified. Genomic DNA was extracted from each sample according to the DNA extraction method described below. As primers for amplifying Fusarium Ntag, the oligonucleotide represented by the nucleotide sequence set forth in SEQ ID NO: 21 and the oligonucleotide represented by the nucleotide sequence set forth in SEQ ID NO: 22 (FIG. 9) were used. Fusarium Ntag was amplified by PCR using the genomic DNA as a template and the pair of primers. The amplified DNA fragment was purified and the nucleotide sequence was decoded.

  The analyzed Ntag sequence was searched using the amino acid sequence of POLA1 protein as a query using NCBI's pblastn web server. As a result, the amino acid sequence encoded by the base sequence of the DNA fragment amplified as described above using Fusarium Race1-2 was identical to the Fusarium Race1-2 amino acid sequence registered in the computer database. Further, the amino acid sequence encoded by the base sequence of the DNA fragment amplified as described above using Fusarium Race4 as a sample matched the amino acid sequence of Fusarium Race4 registered in the computer database. Thus, using the amino acid sequence encoded by Ntag as an index, Fusarium could identify Race1-2 and Race4 that infect bananas.

(11) Homology between PBL and PBR sequences In different species, PBL and PBR sequences were compared and their homology was examined. As shown in FIG. 10, PBL and PBR sequences were compared between human and Arabidopsis thaliana and showed 95% and 69% homology, respectively. Comparison of PBL and PBR sequences between Giardia and Arabidopsis thaliana showed 70% and 63% homology, respectively. PBL and PBR sequences were compared between Malaria and Arabidopsis thaliana and showed 70% and 50% homology, respectively. PBL and PBR sequences were compared between Theileria and Arabidopsis thaliana and showed 85% and 69% homology, respectively. PBL and PBR sequences were compared between Naegleria and Arabidopsis thaliana and showed 65% and 56% homology, respectively. PBL and PBR sequences were compared between human and Giardia and showed 65% and 69% homology, respectively. The PBL and PBR sequences were compared between human and malaria parasites and showed 70% and 56% homology, respectively. PBL and PBR sequences were compared between rice and malaria, showing 70% and 63% homology, respectively.

  As described above, eukaryotic species or subspecies can be identified by using the Ptag sequence as an index. In order to elucidate the speciation of an organism, it is important to analyze a large number of DNA markers contained in the genome and proceed comprehensively, but analyze a large number of DNA markers for the organism being studied. Costs money and effort. In order to use the DNA base sequence analysis method as an auxiliary means for determining the species of an organism, it is effective to use a small number of base sequences as proposed in DNA barcoding. If it is a small number of base sequences, it can be easily analyzed and it is considered easy to construct a database. However, when the DNA base sequence is used for species determination, it is ambiguous where to delimit the base sequence homology boundary. On the other hand, when an amino acid sequence is used, only non-synonymous base substitutions are reflected in the amino acid sequence, so that the boundary of molecular biological classification can be clearly determined. In this example, as a result of analysis of several strains belonging to the same species, in Candida albicans and Cryptococcus neoformans, which belong to the genus Coccidioides, the strains belonging to the same species had the same Ptag sequence (Table 3). On the other hand, in cultivated rice (Oryza sativa), amino acid substitution of 2 residues was observed in the Indian and Japanese Ptag sequences classified into two ecotypes (Table 4). I don't know how much the classification of Linne species corresponds to the variation of the Ptag sequence, but groups with the same Ptag sequence are grouped into one molecular biological classification: ipsum (identical protein sequence unit member) It might be possible to define

  The materials and methods used in this example are described below.

1) Extraction of plant material and genomic DNA The materials shown in Table 1 above were used as test materials such as rice genus, barley genus and cherry genus. 100 mg of the leaves of the test material was placed in a 2 ml tube, frozen with liquid nitrogen, and pulverized using a multi-bead shocker (manufactured by Yasui Kikai Co., Ltd.). Total genomic DNA was obtained from the CTAB (Cetyltrimethil ammmonium bromide) method (Doyle, JJ et al., “A rapid DNA isolation procedure for small quantities of fresh leaftissue”, Phytochemical Bulletin, 1987, Vol. 19, It extracted using the modified method of p.11-15).

2) PCR amplification and direct sequencing A plant DNA fragment containing the PolA1 gene exon 20 was amplified by PCR using a pair of primers (Table 1). Primer sequences were designed with reference to EST data such as Arabidopsis, rice, wheat and almonds. Amplification of the DNA fragment was carried out for 40 cycles using a PCR plate PTC200 (manufactured by MJ Research) under conditions of denaturation 94 ° C. for 1 minute, annealing 58 ° C. for 1 minute and extension at 72 ° C. for 2 minutes. ExTaq DNA polymerase (manufactured by TaKaRa Co., Ltd.) was used as the thermostable DNA polymerase.

  The amplified DNA fragment was subjected to 1.2% agarose gel electrophoresis to confirm its amplification, and purified using a QIAquick PCR purification kit (Qiagen). The purified DNA fragment was reacted using Big Dye Terminator Cycle Sequencing Kit (Applied Biosystems) and sequence primer (Table 1, Fig. 8), and the nucleotide sequence was decoded using ABI3100 sequencer (Applied Biosystems). .

3) Analysis of nucleotide sequences The Ntag sequences of various eukaryotes were searched using the NCBI pblastn web server as a query for the amino acid sequence of POLA1 protein (Altschul, SF et al., "Basic local alignmentsearch tool", Journal Of Molecular Biology, 1990, Vol. 215, p.403-410). Since the full-length Ntag sequence could not be detected from the EST database, the Ntag sequence was identified using the base sequence data extracted from the full-length genome or genome survey sequence database. Detailed analysis of the base sequence was performed using DNASIS (manufactured by Hitachi) and Genentyx (manufactured by Softoware). Nucleotide sequence alignment is shown in DDBJ's Clustal W (Thompson, JD) et al., “CLUSTAL W: improving the sensitivity of progressive multiple sequence alignment through sequence weighting, position-specific gap penalties and weight matrix choice”, Nucleic Acids Research, 1994, Vol. 22, No. 22, p.4673-4680).

4) Creation of molecular phylogenetic tree Molecular phylogenetic analysis of the amino acid sequence of exon 20 of the plant PolA1 gene and various eukaryotic Ptag sequences was performed by MEGA4 (Tamura, K. et al., MEGA4: Molecular Evolutionary Genetics Analysis MEGA Software. Version 4.0 ”, Molecular Biology and Evolution, 2007, Vol. 24, pp.1596-1599). Data aligned by Clustal W was input to MEGA4 and a molecular phylogenetic tree was created using the neighborhood distance coupling method. In creating the phylogenetic tree, bootstrap values were obtained using 500 data.

  The accession numbers of various eukaryotic base sequence data used in this study are listed in Table 3 above.
