Plant hormones are a group of chemically diverse molecules that control virtually all aspects of plant development. Classical plant hormones were identified many decades ago in physiology studies that addressed plant growth regulation. In recent years, biochemical and genetic approaches led to the identification of many molecular components that mediate hormone activity, such as hormone receptors and hormone-regulated genes. This has greatly contributed to the understanding of the mechanisms underlying hormone activity and highlighted the intricate crosstalk and integration of hormone signalling and developmental pathways. Here we review and discuss recent findings on how hormones regulate the activity of shoot and root apical meristems.
植物激素是一类化学性质多样的分子,几乎控制着植物生长发育的各个方面。经典的植物激素在几十年前的生理学研究中被发现,这些研究主要关注植物生长的调节。近年来,生化和遗传方法的应用导致了许多介导激素活性的分子成分的鉴定,如激素受体和激素调控基因。这极大地促进了对激素活性的机制的理解,并强调了激素信号转导和发育途径的复杂串扰和整合。在这里,我们综述和讨论了最近关于激素如何调节茎尖和根端分生组织活性的发现。
