Function
Is required for normal leaf, flower and seed development and controls cotyledon and leaf patterning by inhibiting premature differentiation. Regulates the expression of a subset of PcG target genes. Is required for the repression of the floral specific genes PI, SEP2, and SEP3, but also for the activation of FLC (PubMed:20647345). Involved in response to cold. Involved in the regulation of COR15A, COR15B, BAM3 and AMY3 transcripts, and ascorbate levels in response to prolonged chilling temperatures (PubMed:20674078).
