[0036] 1. Materials and methods

[0037] 1.1 Transcriptome data sources

[0038] The transcriptome data of the Sorbus tree came from the results of Illumina high-throughput sequencing of Sorbus tree leaves by the inventor's research group in 2014. The leaves of three 5-year-old Sorbus trees were used for sequencing, RNA was extracted, and Shanghai Boha...

Abstract

The invention relates to the field of molecular biology, in particular to sorbus pohuashanensis EST-SSR markers, primers thereof and application. The primer pairs of the molecular markers can be used for identifying allele polymorphism and same or relevant plants, distinguishing the plants and researching the genetic diversity of populations. The molecular markers can be also used for heredity and phenotype research by adopting a statistical method, for example, linkage analysis, QTL positioning, genealogical confirmation, genetic polymorphism research of populations, and chain imbalance. The information can be used for identification of specific traits of plants and/or construction of new varieties of molecular identity cards.

Description

technical field [0001] The invention relates to the field of molecular biology, in particular to a rowan tree EST-SSR marker, a pair of primers and applications thereof. Background technique [0002] Simple sequence repeat (SSR), also known as microsatellite marker, is a type of DNA sequence composed of tandem repeating units of 1 to 6 nucleotides. SSR markers have the advantages of high polymorphism, co-dominance, reproducibility and high stability. They are currently one of the most valuable molecular markers and are widely used in the fields of human medicine, animals, plants and microorganisms. However, the species-specificity of SSR markers limits the generality of its primers to a certain extent. For species with unknown gene sequences, the development of SSR markers is more difficult. The traditional SSR marker development is mainly based on gene library construction method (including SSR enrichment library), the experimental process is complicated, time-consuming an...
