Source Description
TAIREncodes TRICHOMELESS1 (TCL1), a single-repeat MYB-type transcription factor that negatively regulates trichome formation by suppressing GL1 (GLABRA1). In a tandem repeat with AT2g30424 and AT2g30420.
UniProtMYB-type transcription factor involved in trichome cell specification. Acts as a negative regulator of trichome patterning and formation by direct binding to the cis-acting regulatory elements of GL1, thus suppressing the expression of GL1. {ECO:0000269|PubMed:17933793}.
