Comment typeDescription
Developmental StageExpressed at the earliest stages and throughout LSM initiation and development. In embryo development, expressed at the heart stage until the 'walking stick' stage in the adaxial portion of the cotyledon primordia, the shoot apical meristem (SAM) and the vascular precursor cells of the hypocotyl and root. In developing flowers, expressed first at stage 1 in the center of L3 layer and then expands to the center of L2 and L1 layers. Expressed in the center of flower meristem through stages 4 and 5. At stage 6, expressed in the adaxial side of the carpel primordia and then on the adaxial carpel face. {ECO:0000269|PubMed:11169198}.
Disruption PhenotypePlants display strongly reduced auxin polar transport in inflorescence stems and hypocotyls. This phenotype is probably due to altered cell differentiation and morphology. {ECO:0000269|PubMed:11402186}.
FunctionProbable transcription factor involved in the regulation of interfascicular fiber (cortical cells) and secondary xylem differentiation in the inflorescence stems. Required for lateral shoot meristems (LSMs) and flower meristems (FMs) initiation. May be involved in the determination of vascular patterning and organ polarity. {ECO:0000269|PubMed:10559440, ECO:0000269|PubMed:11169198, ECO:0000269|PubMed:11402186, ECO:0000269|PubMed:15111711, ECO:0000269|PubMed:15598805, ECO:0000269|PubMed:7555701}.
