Abstract:

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.

Key words: rice, pollen exine, sporopollen
