Abstract: The plant life cycle includes two parts: vegetative growth and reproductive growth. The reproductive development can be divided into three stages: the flowering development, the development and formation of gametophyte, fertilization and the formation of zygote. 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.

Key words: plants, reproduction development, flowering development, gene regulation
