The mature form of a plant shoot system is an expression of several genetically controlled traits, many of which are also environmentally regulated. A major component of this architectural variation is the degree of shoot branching. Recent results indicate conserved mechanisms for shoot branch development across the monocots and eudicots. The existence of a novel long-range branch-inhibiting signal has been inferred from studies of branching mutants in pea and Arabidopsis.

芽分支。

植物芽系统的成熟形式是几种遗传控制性状的表达，其中许多也是环境调控的。这种结构变化的主要组成部分是枝条的分支程度。最近的结果表明保守的机制，整个单子叶植物和双子叶植物的枝条发育。从豌豆和拟南芥中的分支突变体的研究中推断出了新型的远距离分支抑制信号的存在。
