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.
植物地上部系统的成熟形态是多种受基因控制的性状的一种表现,其中许多性状也受环境调控。这种结构变异的一个主要组成部分是地上部分支程度。最近的研究结果表明,单子叶植物和双子叶植物在地上部分支发育方面存在保守机制。从对豌豆和拟南芥分支突变体的研究中推断出一种新型长距离分支抑制信号的存在。
