Coordinated histone variant H2A.Z eviction and H3.3 deposition control plant thermomorphogenesis
The effect of temperature on plant morphology is known as thermomorphogenesis. The phytohormone auxin is important for thermo-induced cell elongation. In Arabidopsis thaliana, Phytochrome-Interacting Factor 4 (PIF4) forms the central hub of the thermal response pathway and directly regulates auxin synthesis gene expression at high temperature. The activity of PIF4 is linked with chromatin regulation, […]
