An MRG-mediated chromatin switch operates at the SOC1 gene to modulate abiotic stress responses during the onset of flowering

ABSTRACT: The mechanisms underlying the precise integration of environmental and developmental signals necessary for plant adaptation to suboptimal environments remain obscure. Here we show that a chromatin switch, mediated by MRG proteins, acts on the floral activator SUPPRESSOR OF OVEREXPRESSION OF CO 1 (SOC1) to coordinate flowering initiation with plant responsiveness to adverse conditions. SOC1 constitutes a central hub in a mechanism that tunes down stress responses likely to optimize plant reproductive success and fitness
