主 题：gibberellins DELLAs hormone crosstalk plant development phenotypic plasticity
摘 要：Plant phenotypic plasticity is controlled by diverse hormone pathways, which integrate and convey infor- mation from multiple developmental and environmental signals. Moreover, in plants many processes such as growth, development, and defense are regulated in similar ways by multiple hormones. Among them, gibberellins （GAs） are phytohormones with pleiotropic actions, regulating various growth processes throughout the plant life cycle. Previous work has revealed extensive interplay between GAs and other hor- mones, but the molecular mechanism became apparent only recently. Molecular and physiological studies have demonstrated that DELLA proteins, considered as master negative regulators of GA signaling, inte- grate multiple hormone signaling pathways through physical interactions with transcription factors or reg- ulatory proteins from different families. In this review, we summarize the latest progress in GA signaling and its direct crosstalk with the main phytohormone signaling, emphasizing the multifaceted role of DELLA proteins with key components of major hormone signaling pathways.
