Global Identification of ANTH Genes Involved in Rice Pollen Germination and Functional Characterization of a Key Member, OsANTH3

In pollen germination process, the secretory vesicles deliver cell wall and plasma membrane materials, and excessive materials are sequestered via endocytosis. AP180 N-terminal homology (ANTH) domain-containing proteins function as adaptive regulators for clathrin-mediated endocytosis in eukaryotic systems. However, The role or even the existence of the ANTH gene family in monocot plants is not well understood. Our study will contribute to a comprehensive understanding of the ANTH family in rice and their role in late pollen development.
