植物雌配子体发育研究进展

Research Advances in Plant Female Gametogenesis

高等植物雌配子体的形成涉及孢原细胞和大孢子母细胞的确立与分化、大孢子发生、功能大孢子以及胚囊的形成和发育等多种复杂调控过程。随着当代生物技术及功能基因组学的发展,近年对雌配子体发育的研究已从细胞学描述逐渐过渡到对基因和发育调控分子机理的探索。以拟南芥、水稻和玉米等模式植物为材料进行的相关研究,丰富了人们对于植物雌配子体和其它有性生殖过程遗传调控机理的认识。本文着重阐述了植物雌配子体发生和发育过程,并综述了这一领域最新研究进展。

Female gametogenesis in higher plants undergoes various developmental changes, including the de novo formation of germline cells, the differentiation of the megaspore mother cell, meiosis, megaspore selection, and the development of the embryo sac. Therefore, the system is excellent for dissecting these fundamental processes at both the genetic and molecular levels. This review discusses the recent findings about these processes, with a focus on the model plant Arabidopsis.
