植物生殖发育分子机理简述

摘要

The plant life cycle includes two parts:vegetative growth and reproductive growth .The reproductive development can be di-vided into three stages:the flowering development , the development and formation of gametophyte , fertilization and the formation of zy-gote.From the survival in the environment and the process of overall development , the development of seed also was part of the plant′s development .Plant growth at different stages has different genes regulatory networks and molecular regulation mechanism , the related gene regulation mechanism was reviewed from the perspective of reproductive growth stages .%植物的生活周期包括两部分：营养生长和生殖生长。其中植物生殖发育又包括三个阶段：花的发育，配子体的形成与发育，传粉受精与合子的形成。从在环境中生存的角度和整体植物学发育的进程来看，种子的发育也属于植物的生殖发育。植物发育的不同阶段有不同的基因调控网络和分子调控机理，从生殖发育各个阶段的角度出发综述了相关基因的调控机理。
