Although it is well known that plants respond to UV-B light, how UV-B regulates plant growth and development in an organ-specific manner remains unknown. Two recent reports by Yang et al. and Qian et al. show that the UV-B photoreceptor UVR8 interacts with different MYB transcription factors in arabidopsis (A. thaliana) cotyledons and roots to control cotyledon expansion and lateral root growth, respectively.
虽然人们早已知道植物会对 UV-B 光作出反应，但 UV-B 如何以器官特异性的方式来调节植物生长和发育仍不清楚。最近，Yang 等人和 Qian 等人的两项报告表明，UVR8 这种 UV-B 光受体在拟南芥的子叶和根中分别与不同的 MYB 转录因子相互作用，以分别控制子叶扩张和侧根生长。
