A4 (Wigge) will investigate the plasticity of shoot traits to temperature. Prion-like domains (PrDs) are unstructured protein domains that can undergo liquid-liquid phase separation. Wigge has recently identified a PrD-containing Arabidopsis protein as a thermosensor, and differences in the length of the PrD are associated with different temperature responses. This project will test to what extent variation in PrD-containing proteins underlies differences in reaction norms of shoot traits to temperature in Capsella, using both an untargeted QTL mapping and a candidate-gene approach focused on variable PrD-proteins.
