Combinatorial activities of SHORT VEGETATIVE PHASE and FLOWERING LOCUS C define distinct modes of flowering regulation in Arabidopsis

ABSTRACT: The transition to flowering in plants is controlled by a regulatory network that responds to both developmental and environmental signals. The MADS-box genes FLOWERING LOCUS C (FLC) and SHORT VEGETATIVE PHASE (SVP) are major flowering repressors that enhance responses to environmental cues such as winter temperatures, high ambient temperatures and photoperiod. FLC and SVP physically interact in vivo and mutation of each gene causes early flowering while the double mutant is more extreme. The molecular mechanisms underlying these genetic interactions are mostly unknown. We addressed the regulatory input of these two key transcription factors (TFs) both individually and as a complex at the genome-wide level through ChIP-seq and microarray expression analysis in single and double mutants.
