Negative feedback regulation of UV-B-induced photomorphogenesis and stress acclimation in Arabidopsis.

Proceedings of the National Academy of Sciences of the United States of America - 16 Nov 2010

Abstract excerpt

Plants respond to low levels of UV-B radiation with a coordinated photomorphogenic response that allows acclimation to this environmental stress factor. The key players in this UV-B response are COP1 (an E3 ubiquitin ligase), UVR8 (a β-propeller protein), and HY5 (a bZIP transcription factor). We have shown previously that an elevated UV-B-specific response is associated with dwarf growth, indicating the...
