Description

Grape SSR (simple sequence repeat) marker based on microRNA (micro ribonucleic acid) and application thereof
Technical Field
The invention belongs to the technical field of grape breeding and molecular markers, and particularly relates to a microRNA-based grape SSR marker and application thereof, in particular to application in grape variety identification, cold resistance evaluation and grape breeding.
Background
The molecular marking technology is a common and economical method, and can be used for variety identification and classification, germplasm resource evaluation and screening, auxiliary breeding and other aspects. SSR molecular markers, also called microsatellite (microsatellite) markers, are an analysis method based on simple repeated sequences in DNA sequences, wherein the SSR consists of repeated 2-6 base sequence units, the repeated sequences are widely distributed in a genome, and DNA fragments with polymorphism can be obtained by PCR amplification and analysis of the repeated sequences and are used for identifying the differences among different varieties. The SSR molecular marker technology has low cost, relatively simple and rapid amplification and analysis processes and simpler data analysis, and is suitable for large-scale and rapid sample identification.
The traditional SSR molecular marking method generally adopts polyacrylamide gel electrophoresis for separation and analysis, and in the electrophoresis process, different DNA band modes can appear among different varieties due to the difference of fragment lengths. The method is quick and economical, but mainly relies on the difference of the length and the number of the repeated sequences to perform difference analysis, has low resolution, and cannot capture the variation of the bases in the PCR band. In addition, the fluorescent dye moiety required for electrophoresis is toxic, and the comparison and interpretation of the electropherograms requires experimenters to possess a certain experience and expertise. The traditional molecular marker resolution can not reach single base, in order to make up for the deficiency in quality, the polymorphism analysis combined by a plurality of pairs of marker primers is often adopted to achieve the purpose of accurate identification, and the development time and the economic cost of the molecular marker are greatly increased.
Whole genome high throughput sequencing is a commonly used method for identifying and analyzing DNA sequences of different varieties of grapes, which can provide single base resolution, and can detect subtle variations and diversity in DNA sequences. The continuous development and maturation of gene sequencing technology provides more accurate tools for variety identification and breeding, and accelerates the progress of variety improvement and resource protection. However, when the high-throughput gene sequencing technology is used for identifying grape varieties, the generated data volume is huge, complicated data processing and analysis are required, and the cost of library construction and high-throughput sequencing is high, so that the wide application of the technology is limited.
