ABSTRACT

During their life cycle, almost all organisms on earth are exposed to variation in temperature, either on a daily basis or on a seasonal level. To sense and respond to temperature changes, several molecular mechanisms have evolved, especially in sessile plants. However, while our understanding of temperature perception and response has increased in recent years, we still know only few players in the thermomorphogenesis signaling network. For example, in Arabidopsis thaliana, PHYTOCHROME B (PHYB) and PHYTOCHROME INTERACTING FACTOR 4 (PIF4) are central regulators for high temperature-mediated growth. In contrast, many more is known about cold signalling, where INDUCER OF CBF EXPRESSION 1 (ICE1) and MITOGEN-ACTIVATED PROTEIN KINASE 3 (MPK3)/MPK6 are central regulators. However, how plants distinguish between small changes in temperature, a few degrees more or less relative to the optimal temperature, and adjust their growth accordingly has not been explored.  I will present our latest work on novel protein phosphorylation-based mechanisms involved in early temperature signalling.
