TAIRIn a tandem repeat with AT2G30424 and AT2G30432
UniProtMYB-type transcription factor involved in epidermal cell fate specification. Acts as a negative regulator of trichome development, by mediating lateral inhibition. Promotes the formation of hair developing cells in H position in root epidermis, probably by inhibiting non-hair cell formation. {ECO:0000269|PubMed:15604688, ECO:0000269|PubMed:19818620}.
