利用花药相关基因及启动子创制雄性不育种质研究进展

Research Progress on Production of Male Sterile Germplasm by Genetic Engineering with Anther Developmental Genes or Specific Promoters

杂种优势利用是大幅度提高作物产量、改良作物品质的有效途径,而作物雄性不育及优良的育性恢复种质是利用杂种优势的关键因素。为此,综述了近年来有关花药发育重要基因克隆和功能验证研究方面的重要成果,以及运用植物遗传转化工程创制植物雄性不育种质的进展。同时讨论了利用转基因技术创制作物雄性不育系、恢复系和保持系的技术策略,并对利用植物遗传转化技术创制植物杂种优势利用中"三系"种质的现状进行了分析和展望。

Heterosis is the effective way of increasing crop yield and improving quality,and diverse germplasm of crop male sterility and fertility restoration is one of the key factors in heterosis utilization.This paper reviews the recent research results of the cloning and fuctional verification of anther development genes,and the progress of creating crop male sterile and their corresponding fertility restorer germplasm by genetic transformation engeering with the key genes associated with anther development.It also discusses the technical strategy and reseach priorities of creating plant male sterile lines,and corresponding fertility restore and maintain lines by the plant transgenic technology,as well as the current status and perspective of creating ＂three lines＂ in heterosis utilization in practice by plant genetic engineering.
