Cryptochrome-mediated blue-light signalling modulates UVR8 photoreceptor activity and contributes to UV-B tolerance in Arabidopsis

The Arabidopsis UVR8 photoreceptor is a dimer that monomerizes in response to UV-B. Here the authors show that cryptochromes contribute to UV tolerance and facilitate UVR8 redimerization via induction of RUP proteins in response to blue light, modifying UV-B signalling in polychromatic light environ...

Sumario:The Arabidopsis UVR8 photoreceptor is a dimer that monomerizes in response to UV-B. Here the authors show that cryptochromes contribute to UV tolerance and facilitate UVR8 redimerization via induction of RUP proteins in response to blue light, modifying UV-B signalling in polychromatic light environments.
