Ultraviolet-B (UV-B) light suppresses hypocotyl elongation. Although UV-B photo-perception mechanisms have been well investigated, the signaling events from UV-B photoreceptor to downstream transcription are largely unknown. Two recent papers illustrate that the UV-B photoreceptor directly inhibits its interacting transcription factors and reveal the missing link between UV-B perception and transcriptional regulation.

照亮细胞核：UVR8与更多物质相互作用

紫外线B（UV-B）抑制下胚轴伸长。尽管已经对UV-B光感知机制进行了深入研究，但是从UV-B光感受器到下游转录的信号转导事件还是非常未知的。最近的两篇论文表明，UV-B感光体直接抑制了其相互作用的转录因子，并揭示了UV-B感知与转录调控之间的缺失联系。
