Abstract
Male fertility in angiosperms requires specific spatiotemporal gene expression patterns and cellular differentiation during male reproductive development ([Wilson and Zhang, 2009][1]; [Lin et al., 2017][2]). The formation of the male gametophyte begins inside the anther with the formation of a large

Male fertility in angiosperms requires specific spatiotemporal gene expression patterns and cellular differentiation during male reproductive development (Wilson and Zhang, 2009; Lin et al, 2017)
In this issue of Plant Physiology, Zhao et al (2020) characterized a gene, Rice Male Sterile2 (RMS2, encoding a GDSL lipase protein), that is required for anther development and pollen fertility by affecting tapetal degradation, the formation of anther cuticle and pollen exine, and central vacuole development (Zhao et al, 2020)
Deletions and substitution at RMS2 resulted in rice (Oryza sativa) male sterility with abnormal anther and pollen phenotypes
