	       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.
