Within this broad topic we are particularly interested in characterising (i) the molecular mechanism by which these photoreceptors mediate light - dependent entrainment of the circadian clock, (ii) the components mediating, in a light - quality - dependent fashion, nucleocytoplasmic partitioning of phytochromes and UVR8, (iii) how phosphorylation and sumoylation of these photorecepors and other signalling components modulate red / far - red and UVB - induced signalling, and (iv) to what extent intercellular and cell - autonomous events contribute to phytochrome and UVR8 regulated photomorphogenesis.
