PHYLOGENETIC CLASSIFICATION METHOD OF ALLIUM VEGETABLE
GENETIC RESOURCES BASED ON DIFFERENT MOLECULAR MARKERS
AND USE THEREOF
TECHNICAL FIELD
[0001] The present disclosure belongs to the technical field of phylogenetic classification for resources, in particular to a phylogenetic classification method of
Allium vegetable genetic resources based on different molecular markers and use thereof.
BACKGROUND ART
[0002] At present, Allium vegetables are mostly classified based on single gene fragments at a molecular level. Due to a limited amount of data carrying less genetic information, there are often certain defects in the classification of species with minimal interspecific differences, restricting the development of classification and identification as well as resources utilization for the A/lium vegetables.
[0003] Through the above analysis, the existing problems and defects in the prior art are as follows: at present, the A/lium vegetables are mostly classified based on single gene fragments at the molecular level. Due to the limited amount of data carrying less genetic information, there are often certain defects in the classification of species with minimal interspecific differences, restricting the development of the classification and identification as well as the resources utilization for the Allium vegetables.
[0004] The significance of solving the above problems and defects 1s as follows: to analyze differences in classification results of A/lium vegetable genetic resources based on different sequence sets, to seek a method suitable for classification, identification and phylogeny of the Allium vegetable genetic resources, thereby providing new ideas for subsequent researches of the Allium vegetable genetic resources.
SUMMARY
[0005] Aiming at the problems in the prior art, the present disclosure provides a phylogenetic classification method of Allium vegetable genetic resources based on different molecular markers and use thereof.
[0006] The present disclosure includes the following steps:
[0007] step 1, selection of test materials;
[0008] step 2, extraction and detection of a plant genomic DNA;
[0009] step 3, amplification and sequencing of a sequence;
[0010] step 4, assembly and feature analysis of the sequence; and
[0011] step 5, construction of a phylogenetic tree.
[0012] Further, in step 1, the test materials of the Allium vegetable genetic resources may be derived from the Mid-Term Bank of National Vegetable Germplasm Resources, the National Asexual Propagation and Perennial Vegetable Germplasm resources Garden and the Germplasm Bank of Wild Species.
[0013] Further, in step 2, the extraction and detection of a plant genomic DNA may include:
[0014] Extracting the plant genomic DNA, followed by detection with 1% agarose gel electrophoresis to determine whether the plant genomic DNA is successfully extracted and a mass of the plant genomic DNA.
[0015] Further, in step 3, the amplification and sequencing of a sequence may include: amplification of an internal transcribed spacer (ITS) sequence, an rps 16 intron sequence, and a tmL-F intergenic region sequence.
[0016] Further, in step 4, the sequence may be subjected to the assembly and feature analysis.
[0017] Further, in step 5, the phylogenetic tree may be constructed.
[0018] Combined with all the above technical solutions, the present disclosure has the advantages and positive effects as follows: the present disclosure provides a phylogenetic classification method of Allium vegetable genetic resources based on different molecular markers; through comparative analysis of a chloroplast genome of main A/ium plants, it is found that a rps16 intron and a trnL-F intergenic region in the chloroplast genome are highly variable regions due to obvious sequence differences; the present disclosure provides more locus information for classification and identification, genetic differences and phylogeny of species.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] Aiming at the problems in the prior art, the present disclosure provides a phylogenetic classification method of Allium vegetable genetic resources based on different molecular markers and use thereof. The present disclosure will be described in detail below in conjunction with the accompanying drawings.
[0029] As shown in FIG. 1, the phylogenetic classification method of Allium vegetable genetic resources based on different molecular markers includes the following steps:
[0030] S101, selection of test materials;
[0031] S102, extraction and detection of a plant genomic DNA;
[0032] S103, amplification and sequencing of a sequence;
[0033] S104, assembly and feature analysis of the sequence; and
[0034] S105, construction of a phylogenetic tree.
[0035] The present disclosure is further described below with reference to specific examples.
[0036] 1. Overview of the present disclosure
[0037] In the present disclosure, through comparative analysis of a chloroplast genome of main A/lium plants, it is found that a rps 16 intron and a trnL-F intergenic region in the chloroplast genome are highly variable regions due to obvious sequence differences, the present disclosure provides more locus information for classification and identification, genetic differences and phylogeny of species.
[0038] 2. Materials and methods
[0039] 2.1. Test materials
[0040] 78 test materials of the Allium vegetable genetic resources are derived from the
Mid-Term Bank of National Vegetable Germplasm Resources, the National Asexual
Propagation and Perennial Vegetable Germplasm resources Garden and the Germplasm
Bank of Wild Species, including a total of 28 species of common A//ium vegetables, such as Allium tuberosum, Allium fistulosum L. var. gigantum Makino, Allium fistulosum L. var. caespitosum Makino and Allium cepa L., covering 7 groups classified under the genus Al/ium in China (Table 1).
[0041] Table 1 Test materials
[0042] 2.2. Extraction and detection of a plant genomic DNA
[0043] The plant genomic DNA is extracted, followed by detection with 1% agarose gel electrophoresis to determine whether the plant genomic DNA is successfully extracted and a mass of the plant genomic DNA.
[0044] 2.3. Amplification and sequencing of a sequence
[0045] In the present disclosure, amplification primers of an ITS sequence are designed by WHITE and the like, including universal primers, forward primers and reverse primers. The amplification primers of the rpsl6 intron sequence use the forward primer and reverse primer designed by OXELMAN, and the amplification primers of the trnL-
F gene spacer sequence use the forward primer and reverse primer designed by
TABERLET et al. the primers are synthesized by BGI Group (Beijing). An amplification reaction system is set to 50 pL.
[0046] 3. Results and analysis
[0047] 3.1. Amplification results of the sequence
The ITS sequence is amplified by primers ITS1 and ITS4 using the genomic DNA of 78
Allium vegetable genetic resources samples as templates. FIG. 2(a) shows a partial amplification result: at a standard molecular weight of about 700 bp, each sample has a clear band, which can be considered as an ITS sequence of a target band. FIG. 2(b) shows a partial amplification result of the rps16 intron sequence at a standard molecular weight of about 800 bp. Similarly, PCR products of the tmL-F intergenic region of the 78 Allium vegetable genetic resources are as shown in FIG. 2(c), exhibiting a partial amplification result of the materials.
[0048] 3.2. Feature analysis of the sequence 5 [0049] A sequence length and a guanine-cytosine (GC) content are counted for the ITS, rps16 intron and trnL-F intergenic region of the 78 different Allium vegetable genetic resources (Table 2). The lengths of ITS sequences of all the test materials are between 625-687 bp, where Allium wallichii Kunth in a Sect. Bromatorrhiza group has the longest sequence, and Allium fistulosum L. var. viviparum Makino in a Sect. Schoenoprasum group has the shortest sequence, and a difference between the above two is only 62 bp.

[0051] 3.3. Phylogenetic analysis
[0052] 3.3.1. Classification results of A/lium vegetable genetic resources based on ITS sequence
[0053] A phylogenetic tree of 78 Allium vegetable genetic resources is constructed by a nuclear gene ITS sequence (FIG. 3). The results show that the 4//ium vegetable genetic resources in each group can be basically distinguished.
[0054] 3.3.2. Classification results of Allium vegetable genetic resources based on rps 16 intron sequence
[0055] A phylogenetic tree of 78 Allium vegetable genetic resources is constructed by a chloroplast gene rps16 intron sequence (FIG. 4). Materials of a Sect. Porrum group are gathered into one, including four kinds: Allium sativum, Allium ampeloprasum L., Allium longicuspis, and Allium porrum.
[0056] 3.3.3. Classification results of Allium vegetable genetic resources based on trnL-
F intergenic region sequence
[0057] A phylogenetic tree of 78 Allium vegetable genetic resources is constructed by a chloroplast gene trnL-F intergenic region sequence (FIG. 5). The Allium sativum,
Allium ampeloprasum L., Allium longicuspis, and Allium porrum in the materials are grouped into a same branch, forming the Sect. Porrum group, which are more closely related; while one Allium porrum is divided into the Sect. Schoenoprasum group.
[0058] 3.3.4. Classification results of Allium vegetable genetic resources based on
ITS-+rps16+trnL-F sequence
[0059] A phylogenetic tree of 78 Allium vegetable genetic resources is constructed by an ITS+rpsl6+tmL-F sequence (FIG. 6)Most of the Allium sativum, Allium ampeloprasum L., Allium longicuspis, and Allium porrum in the materials are grouped into a same branch, forming the Sect. Porrum group, which are more closely related; while there are also a small amount of materials that have been aggregated into other groups. Table 3 shows classification and comparison of 78 Allium vegetable genetic resources based on different molecular markers.
