摘要/Abstract

摘要：

植物侧枝的发育在植物形态建成中具有十分重要的地位，侧枝的形态直接影响植物的产量。侧枝的发育由生长点干细胞持续分裂和分化形成，包括侧生分生组织特化，侧生分生组织起始和侧生分生组织外生。侧枝的发育受到内部生长因子和外部环境信号的共同调节。文中总结了侧枝发育过程中侧生生长点干细胞起源、形成和休眠等过程的基本问题，综述了转录因子、激素、表观遗传、外界环境共同决定侧生分生组织形成和发育中的作用机制，为探讨植物侧枝的形成机理提供参考。

Abstract:

The development of plant branches is crucial to plant morphology, and the shape of side branches directly affects its yield. The development of side branches is formed by the continuous division and differentiation of stem cells at the growth point, including lateral meristem specialization, lateral meristem initiation and lateral meristem outgrowth. It is jointly regulated by internal growth factors and external environmental signals. This article systematically sums up the basic issues of the origin, formation and dormancy of lateral growth point stem cells during the development of side branching, then also summarizes the mechanism of the formation and development of lateral meristems determined by co-action of transcription factors, hormones, epigenetics, and external environment that determine, providing a reference for exploring the formation mechanism of plant side branches.

Key words: side branching, transcription factor, plant hormone, environmental factor, epigenetics
