OsPS6 Plays Important Role in Anther Development and Microspore Formation

In flowering plants,the alternating life cycle between diploid sporophyte and haploid gametophyte generations is completed through the synergistic action of sporophyte and gametophyte.The formation of viable pollen grains in anther cavity is the key to the process(Scott et al,2004;Ma,2005;Wilson and Zhang,2009).The four-layer anther wall has specific functions and coordination in the whole process,and plays an important role in the formation of pollen grains(Walbot and Egger,2016).
