Summary: | Cytokinins are important signalling molecules in plants, and recent studies have begun to shed light on the molecular mechanisms underlying their biosynthesis and response pathways. However, from the time of their discovery, it has been clear that cytokinins interact with other signals to regulate plant growth and development. Herein the interaction of cytokinin with three other signals: light, ethylene, and auxin is discussed. The interaction between light and cytokinin signalling, highlighted by recent analysis of cytokinin signalling mutants is reviewed. A discussion of another aspect of cytokinin cross‐talk, its induction of ethylene biosynthesis in etiolated Arabidopsis seedlings, and recent studies that have begun to elucidate the mechanism underlying this regulation is also presented. Finally, there is a brief review of the interaction of auxin and cytokinin, and present novel expression profiling data of Arabidopsis seedlings treated with combinations of these two hormones, which provide insight into this interaction. |
