摘要
种子胎萌是内在的遗传基础和外部环境共同作用的结果,受许多基因的调控和植物激素的影响。近些年来,随着分子生物学的快速发展,种子胎萌研究已经深入到分子水平。分子生物学技术的运用,特别是基因的克隆与表达、植物激素的生物合成与信号转导和分子遗传学等手段已成为研究种子胎萌的新工具和新方向。现从种皮色泽基因R、矮杆基因Rht3以及Viviparous(Vp)基因家族等方面就种子胎萌相关基因与胎萌关系进行了综述;并对植物激素脱落酸(ABA)和赤霉素(GA)的生物合成或信号转导在种子胎萌的调控中的作用等方面进行综述。
Seed vivipary is a complex result of heredity and environment, which is influenced by a large number of genes and phytohormones. Molecular biology techniques, such as gene cloning and expression, biosynthesis and signal transduction of hormones and molecular genetics, are useful approaches for the analysis of mecha- nism of seed vivipary. This paper briefly summarized the advances on the relationship between related genes such as seed coat gene R, thumb gene Rht3 and Viviparous （Vp） gene family and vivipary in plant seeds and the role of ABA, GA biosynthesis and signal transduction in seed vivipary.
