混合池测序在水稻深根比QTL验证中的应用研究
Application of Mixed Pool Sequencing in QTL Verification of Rice Deep Root Ratio
摘要
Abstract
The root system of rice is a key organ for nutrient absorption and growth,and a strong root system is an important indicator for cultivating drought resistance in rice.In order to cultivate excellent rice varieties,mixed pool sequencing method was used to sequence rice samples,and sample screening and labeling were carriedout through inter parent polymorphism to mine quantitative trait loci(QTLs)for root traits in rice.The results showed that among the parental polymorphism markers,486 SSR molecular markers were used to analyze parental polymorphism,with the highest proportion of polymorphism being 43.20％.In QTL mapping of rice,5 candidate genes were indentified to be specifically expressed at the root tip and related to the growth angle of the root tip,indicating a close relationship between these genes and the deep root ratio of rice.关键词
