Transcription factor involved in the regulation of fruit patterning (PubMed:22946675). Promotes replum development by down-regulating JAG and YAB1/FIL genes activity in medial tissues (PubMed:22946675). Seems to inhibit fruit dehiscence, maybe by controlling valve margin lignification (PubMed:22946675). Promotes callus formation at wound sites (PubMed:34730809). Is required for the formation of highly vacuolated large cells in callus and for the establishment of organ reconnection (PubMed:34730809). Targets directly genes involved in stress-induced cellular reprogramming, and cell wall modifier genes (PubMed:34730809). Expressed in lateral roots, cotyledon and root vasculatures, pericycle, stem cells of the primary root meristem, leaf primordia, flower vasculature, stigma and gynoecium (PubMed:18950478, PubMed:22946675). Expressed in developing carpels, floral buds and inflorescences (PubMed:22946675). Induced by wounding. Early flowering (PubMed:18950478). Altered fruit development (PubMed:22946675). Siliques with narrow replum (PubMed:22946675). Reduced number of lateral roots (PubMed:22946675). Belongs to the WUS homeobox family.
