Rice anther development is composed of a series of complex biological processes, among which tapetum cells play an important role in anther development

The Chu Chengcai research group of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences and the Tong Hongning research group of the Chinese Academy of Agricultural Sciences have jointly identified a pollen sterility mutant post ( polen sterility )

Figure 1: The tapetum PCD process is delayed in the post mutants, leading to delayed degradation of the tapetum layer, leading to pollen abortion

Figure 2: Fine regulation of POST can improve rice grain weight
