玉米雄性不育机理及其在工程核不育制种中的应用
Molecular Mechanisms of Male Sterility and their Applications in Biotechnology-based Male-sterility Hybrid Seed Production in Maize
摘要
Abstract
Maize(Zea mays)is the major grain crop with the largest planting area and the highest total yield in China,and it is also a model of heterosis utilization.However,compared with developed countries,China is still facing several out-standing problems in maize production,such as low average yield,lack of breakthrough varieties and high cost of hybrid seed production.The main solution to these problems is the application of male-sterile lines with better heterosis utiliza-tion efficiency and thus increase the yield per unit area of maize.In this review,we summarize the latest advances of male sterility research in maize,including its classification,gene cloning and functional analysis,molecular regulatory network construction,and discuss the strategies of creating novel male-sterility systems and their potential/future application in maize breeding.This review provides guidelines for the male-sterility based/assisted hybrid breeding and seed production in maize.关键词
