摘要
在对构建植物基因工程雄性不育基因的几种技术路线及其保持和恢复措施进行概述的基础上,分析了转基因雄性不育的遗传特征及影响不育基因表达效果的因素;指出了国内当前研究中应当注意的问题,并提出了应注重创新、减少重复,走产学研相结合之路,缩短研究与应用的距离,加强对自发突变雄性不育基因的转基因应用研究等建议;同时对其应用前景进行了展望,认为基因工程雄性不育很有可能成为植物雄性不育利用的主流。
The strategy for constructing plant male sterile genes by genetic engineering as while as the maintaining and restoring methods of the male sterility were generalized.The hereditary property of transgenic male sterile genes and the factors affecting the expression of them were analyzed.Issues deserving of attention in the research in our country and author＇s suggestions were put forward,including paying attention to innovation,reducing duplication,combination of research,production and teaching,shorten the distance of research and application,strengthen the application and research on transgenic of spontaneous matant male sterility and so on.The application prospects of transgenic male sterility were discussed.It＇s considered that genetically engineered ones will probably be the main type of male sterile genes applied in plant breeding.
