Abstract:

Female gametophyte development is an important prerequisite for sexual reproduction in flowering plants, including two key events, macrosporogenesis and female gametophyte development. The development of the female gametophyte determines whether the plant can be properly fertilized and complete the reproduction of generations. Auxin is a widespread phytohormone in plants, and the polar distribution of auxin in the ovule ensures the normal development of the ovule. However, due to the complexity of the auxin signaling pathway and the fact that female germ cells are located inside the tissues, the regulatory network and molecular mechanism of the auxin signaling pathway in the female germline are still unclear. In this paper, we summarize the studies related to auxin synthesis, dynamic equilibrium and signaling, and review the studies on auxin regulation of macrosporogenesis and female gametophyte genesis. The aim of this paper is to provide a reference for the further study of the auxin signaling pathway on female germline establishment.
