Source Description
UniprotTISSUE SPECIFICITY: Expressed in trichomes, at the base of many lateral organs, including branching points of the inflorescence and floral organs and in the distal part of the pistil at stages when style and stigma start to develop. Also detected in pedicels and at the base of petals and sepals. {ECO:0000269|PubMed:15821980}.
Functional Description ? help Back to Top
Source Description
TAIREncodes LOB domain protein whose overexpression results in KNOX gene repression. Overexpression also results in plants with hyponastic leaves, downward pointing flowers and reduced apical dominance. May be involved in the transcriptional regulation of the homeobox gene BP (brevipedicellus) during lateral organ differentiation. Acts together with AS2 in proximal-distal symmetry determination.
UniProtControls the proximal-distal patterning in petals and the adaxial-abaxial determination of leaves. Involved in the repression of the homeobox gene BP. {ECO:0000269|PubMed:12787254, ECO:0000269|PubMed:15821980}.
