Genome-Wide binding sites of two MADS-domain transcription factors SOC1 and SVP in Arabidopsis during the floral transition

ABSTRACT: The floral transition in Arabidopsis is tightly controlled by complex genetic regulatory networks in response to endogenous and environmental flowering signals. SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) and SHORT VEGETATIVE PHASE (SVP), two key MADS-domain transcription factors, perceive these signals and function as antagonistic flowering regulators. To understand how they mediate the floral transition, we mapped in vivo binding sites of SOC1 and SVP using chromatin immunoprecipitation followed by hybridization to whole-genome tiling arrays (ChIP-chip). Genes encoding proteins with transcription regulator activity and transcription factor activity were the most enriched groups of genes bound by SOC1 and SVP, indicating their central roles in flowering regulatory networks.
