ABSTRACT
To optimize their growth and survival, plants perceive and respond to UV-B
radiation. However, neither the molecular identity of the UV-B photoreceptor
nor the photoperception mechanism is known. An early molecular response to
UV-B radiation involves the direct interaction between UVR8 and COP1, two
key factors regulating UV-B-induced photomorphogenesis. This pathway secures
plant acclimation to UV-B and thus endurance under sunlight. I will present
our current understanding of COP1 and UVR8 function in UV-B perception and
signalling.
