植物激素在植物生长发育中起着重要作用。它们影响类似的过程,但矛盾的是,它们的信号通路的作用是非冗余的。激素信号在基因网络水平上整合,而不是通过信号转导过程中的串扰。与植物激素整合相反,最近的数据表明,光和植物激素途径具有共同的信号成分,这使得光感受器能够影响生长程序。我们提出了植物激素生长素作为多种植物激素的活动的集成商,以控制植物生长对环境的反应的作用。
Plant hormones play a major role in plant growth and development. They affect similar processes but, paradoxically, their signaling pathways act nonredundantly. Hormone signals are integrated at the gene-network level rather than by cross-talk during signal transduction. In contrast to hormone-hormone integration, recent data suggest that light and plant hormone pathways share common signaling components, which allows photoreceptors to influence the growth program. We propose a role for the plant hormone auxin as an integrator of the activities of multiple plant hormones to control plant growth in response to the environment.
