为对辣椒雄性不育分子研究取得的进展有更直观、系统、深入的了解，梳理已鉴定的辣椒核雄性不育(NMS)基因及部分NMS基因分子标记开发，重点阐述近年来核雄性不育基因精细定位及候选基因探究工作;同时回顾辣椒胞质雄性不育(CMS)相关的线粒体不育基因及其关联分子标记和CMS恢复基因分子标记开发，重点概述近年来恢复基因精细定位研究取得的进展。研究指出，精细定位NMS基因，明确候选基因并开发功能标记是辣椒NMS研究的重点，既能为探明辣椒NMS机理奠定基础又可为育种提供高效利用的分子标记。而CMS相较于NMS更为复杂，表现在遗传机制多样且更易受环境影响等方面，因此，从对CMS育性恢复基因的精细定位到基因克隆以及功能研究并探明CMS分子机制还有很长的一段路要走。
Molecular Advancements of Male Sterility in Pepper
In order to have a more intuitive,systematic and in-depth understanding of the progress made in molecular research on male sterility in pepper,we sorted out the identified nuclear male sterility(NMS)genes in pepper and the development of molecular markers for some of the NMS genes,and highlighted the fine mapping of the NMS genes and the exploration of the candidate genes in recent years.Meanwhile,we reviewed the mitochondrial sterile genes related to cytoplasmic male sterility(CMS)and their associated molecular markers,as well as molecular markers developed for CMS fertility restoration genes,with a focus on the progress made in recent years in fine mapping of fertility restoration genes.Finally,it was pointed out that the fine mapping of NMS genes,identification of candidate genes and development of functional markers were the main focuses of NMS research in pepper,which could not only lay the foundation for the exploration of the mechanism of NMS in pepper,but also provided molecular markers for efficient use in breeding.Compared with NMS,CMS is more complex,characterized by diverse genetic mechanisms and more susceptible to environmental influences.Therefore,there is still a long way to go from the fine mapping of CMS restorer-of-fertilitygenes to the cloning of genes and the functional studies to understand the molecular mechanisms of CMS.
