摘　　要：花粉外壁是花粉正常发育的保障,可为小孢子建立结构支持从而保护其免受恶劣条件的影响,其主要由孢粉素组成。花粉外壁的正常发育是一个复杂的多基因表达调控过程,水稻中目前已分离和鉴定出一系列参与到花粉外壁合成特别是孢粉素代谢相关的基因。本文归纳总结了22个与水稻孢粉素合成及运输相关的基因及其功能、分子机制及调控网络,旨为进一步研究水稻雄性生殖发育分子机制提供理论依据。The pollen exine is the guarantee for the normal pollen development,and the main component is sporpollen,which can establish the structural support for the microspore cytoplasm to protect it from harsh conditions.The normal development of the pollen exine is a complex process of multi-gene expression regulation,there are a large number of genes involved in the development of pollen exine,especially the metabolism of sporopollenin,have been isolated and identified in rice.This paper summarized 22 genes related to rice sporopollen synthesis and transport,as well as their functions,molecular mechanisms and regulatory networks,which is aimed to provide a theoretical basis for further research on the molecular mechanism of rice male reproductive development.
