This project explores how plants perceive ultraviolet-B light, focusing on the UVR8 protein, which is essential for UV-B acclimation. The research aims to uncover the mechanisms behind UV-B absorption and its effects on plant survival.
Ultraviolet-B (UV-B) is a key environmental signal that is specifically perceived by plants and promotes UV acclimation and survival in sunlight.
We discovered recently that the Arabidopsis UVR8 protein is absolutely required for UV-B acclimation and functions as the major UV-B photoreceptor in plants:
UVR8 dimer perception of UV-B photons leads to monomerization and direct interaction with the E3 ubiquitin ligase COP1, the central regulator of light signalling.
We proposed that the initial UV-B…
