Cytokinins were discovered in the 1950s by their ability to promote cell division in cultured plant cells. Recently, there have been significant breakthroughs in our understanding of the biosynthesis, metabolism, perception and signal transduction of this phytohormone. These advances, coupled with physiological and other approaches, have enabled remarkable progress to be made in our understanding of the interactions between cytokinin function and environmental inputs. In this review, we first highlight the most recent advances in our understanding of cytokinin biosynthesis, metabolism and signalling. We then discuss how various environmental signals interact with these pathways to modulate plant growth, development and physiology.
细胞分裂素于20世纪50年代被发现，因其具有促进培养的植物细胞分裂的能力。最近，我们对这种植物激素的生物合成、代谢、感知和信号转导的理解有了重大突破。这些进展，再加上生理学和其他方法，使我们在理解细胞分裂素功能与环境输入之间的相互作用方面取得了显著进展。在这篇综述中，我们首先强调了我们对细胞分裂素生物合成、代谢和信号传导理解的最新进展。然后我们讨论各种环境信号如何与这些途径相互作用，以调节植物的生长、发育和生理过程。
