Background technology
Malus spectabilis(Malus spectabilis)It is the rose family(Rosaceae)Malus(Malus)Seeds.Malus spectabilis There is important ornamental plantation to be worth for flower, leaf and fruit, be rare ornamencal flower and tree.
Malus spectabilis kind is classified generally according to the feature of fruit and flower, and fruiting period and time other than the florescence, there are kind mirror Fixed difficult problem.Since the quantity of phenotypic markers and DNA molecular marker is few, existing marking sensitivity is limited, and there are synonyms Identification with homonym phenomenon, Malus, especially Malus spectabilis kind is the difficult point of current research.Malus spectabilis variety source Malus spectabilis breeding, deep development are utilized accurate identification and relevant scientific research has particularly important meaning and value.
Invention content
It is an object of the present invention to provide a kind of methods that Malus spectabilis kind to be measured is identified in identification or auxiliary.
It is provided by the present invention to be used to identifying or assisting the method for identifying Malus spectabilis kind to be measured, it is using in DNA sequence dna Variant sites build nucleic acid molecule formula, and then identify or assist the method for identifying Malus spectabilis kind to be measured, specifically include following step Suddenly:
(1)Using the genomic DNA of Malus spectabilis kind to be measured as template, with two shown in sequence in sequence table 1 and sequence 2 The primer pair of single strand dna composition carries out PCR amplification, obtains PCR product;
(2)The DNA sequence dna that length is 786bp is obtained after the PCR product is sequenced(Clip preceding 19 base and Remaining variation region sequence after 806 bases).Include the change dystopy for disclosing Malus spectabilis product inter-species heritable difference in the sequence Point;
(3)The sequence to be compared is put together with the full sequence in DNA sequence data library, using ClustalX or The softwares such as Mega are compared, and automatically generate a DNA aligned sequences matrix;
The DNA aligned sequences matrix is that two or more sequence opsition dependents are compared row according to specific scoring rule The data set generated after row reflects the similitude between sequence to the maximum extent.The specific scoring rule that is directed to and The correlation common sense such as algorithm and principle are on the books in the monograph in terms of " biological sequence analysis ".The DNA aligned sequences matrix It can directly reflect that each sequence whether there is difference between same nucleotide site, and there are what kind of differences.Find nucleosides The sour discrepant position being listed in the DNA aligned sequences matrix of letter, checks and approves the position and is located at the DNA aligned sequences square The sequence of positions number that battle array 5 ' has been held, that is, determine a polymorphic site.
The DNA sequence dna library is as follows(a1):
(a1)It is made of at least one of sequence in sequence table 3 to sequence 10;Wherein, sequence 3-10 is length 786bp Sequence.
(4)The nucleic acid molecule formula of the Malus spectabilis kind to be measured is listed according to the DNA aligned sequences matrix;

Embodiment 1, using nucleic acid molecule formula identify Malus spectabilis kind method foundation and its application
In order to build the nucleic acid molecule formula that can be used in effectively identifying Malus spectabilis kind, the present inventor is to plunge into the commercial sea One section of non-conservative area's DNA sequence dna is obtained in Chinese bush cherry kind series, and statistical analysis has been carried out to polymorphic site therein.As for examination The Malus spectabilis kind of material totally 10 kinds, it is specific as follows:Clock Northey Malus spectabilis, ' golden wasp ' Mains Zumi, ' Rudoiph ' Malus spectabilis, ' powder roof ' Malus spectabilis, ' flame ' Malus spectabilis, ' diamond ' Malus spectabilis, ' Sprengel professor ' Mains Zumi, ' how meagre profit examines Berman ' Malus spectabilis, ' red long ' Malus spectabilis, ' vertical silk ' Malus spectabilis.
One, design of primers
According to the conserved region at one section of non-conservative area's DNA sequence dna both ends, following primer is designed:
Forward primer:5'- GATTATGCCGAACATAGGAGT -3'(Sequence 1);
Reverse primer:5'- CCAGTGCCCACTTCACC -3'(Sequence 2).
Two, the sequencing of PCR amplification and PCR product
Using the young leaflet tablet of 10 parts of Malus spectabilis kinds as material to be tested as experiment material, carried using plant genome DNA Take kit(Chinese Tiangeng biotechnology(Beijing)Co., Ltd's product, catalog number DP305)Extract each sample material The genomic DNA of material.Using gained genomic DNA as template, PCR amplification is carried out using the primer pair of step 1 design.As a result it shows Show, the PCR product that a length is about 1kb can be obtained in every part of Malus spectabilis kind.
Each PCR product after purification is sequenced, the DNA that the length containing several polymorphic sites is 786bp is obtained Sequence.According to the sequencing result of 10 parts of Malus spectabilis kinds for examination, DNA sequence dna is defined as to the nucleotide sequence of the PCR product 20-805 from 5 ' ends(786bp).By 20th nucleotide note of the nucleotide sequence of the PCR product from 5 ' ends It is the 1st.(Longer or shorter sequence variation may also occur in the high-frequency generation area of this variation, future, may be because The difference of sample to be tested and be slightly changed, at that time can according to actual conditions obtain aligned sequences matrix, determine subsequent polymorphic position The sequence of positions number of point.)
