辣椒雄性不育的分子研究进展

Molecular research progress of male infertility in Capsicum annuum L.

摘要

辣椒(Capsicum annuum L.)是世界上重要的蔬菜作物之一，杂种优势明显。利用雄性不育系制种可有效解决人工去雄的难题，简化制种工序，降低生产成本。而辣椒雄性不育是一个快速发展的研究领域。综述了近几年在辣椒雄性不育的类型与特点、细胞学特征、细胞核雄性不育的分子机制，以及细胞质雄性不育的机制解析等方面所取得的重要进展，并对辣椒雄性不育中存在的问题以及未来发展方向进行了讨论和展望，旨在为辣椒三系配套制种提供理论参考。

Abstract

Pepper (Capsicum annuum L.) is one of the important vegetable crops in the world, with obvious heterosis. Using the male sterile line to produce hybrids can effectively replace manual emasculation, thereby simplifying the seed production process and reducing production costs. The research on male infertility in pepper is a rapidly developing field. We reviewed the important progress in the types, characteristics and cytological features of male infertility, the molecular mechanism of genic male sterile and cytoplasm male sterility in pepper. Further, the problems and development directions of male infertility in pepper were discussed and prospected, aiming to provide a theoretical reference for the three-line system of hybrid seed production for pepper.
