Ultraviolet-B (UV-B) is a relatively minor component of sunlight, but can induce stress-related physiological processes or UV-B-specific photomorphogenic responses in plants. In the last decade, significant progress has been made in understanding the UV-B photomorphogenic pathway, including identification of the key components in the pathway, molecular characterization of UV-B photoreceptor and perception mechanism, and elucidation of the signal transduction mechanisms from the photoactivated UV-B receptor to downstream gene expression. This review summarizes the key players identified to date in the UV-B photomorphogenic pathway and their roles in mediating UV-B signal transduction.
紫外线-B(UV-B)是阳光中的一个次要成分,但可以在植物中诱导与应激相关的生理过程或 UV-B 特异性光形态建成反应。在过去的十年中,人们在理解 UV-B 光形态建成途径方面取得了重大进展,包括鉴定途径中的关键成分、UV-B 光受体的分子特征和感知机制,以及阐明从光激活的 UV-B 受体到下游基因表达的信号转导机制。本综述总结了迄今为止在 UV-B 光形态建成途径中鉴定出的关键参与者及其在介导 UV-B 信号转导中的作用。
