基于基因组重测序的栗属种质资源遗传特性分析
Analysis of the genetic characteristics of Castanea germplasms based on genome resequencing
摘要
Abstract
In this study,genome resequencing technology was employed to conduct an analysis of the genetic characteristics of a total of 180 Castanea germplasms,which included Chinese chestnut(Castanea mollissima)cultivars from 16 provinces in China,as well as European chestnut(Castanea sativa)and Japanese chestnut(Castanea crenata).As a result,48 374 108 genetic variation sites were successfully identified.According to the analysis of these variation sites,the 180 cultivars could be classified into eight major groups.There was a phenomenon of gene introgression among different groups.The population dynamic changes of Chinese chestnut,European chestnut,and Japanese chestnut during the evolutionary process were significantly different.The study also discovered the gene flow of the Chinese chestnut populations from Beijing to Shandong.However,the study has limitations such as uneven distribution of the sample size and limited analysis dimensions.In the future,it is necessary to expand the sample scope and conduct in—depth research by integrating multi—omics approaches.关键词
