Expression -- Description ? help Back to Top
Source Description
UniprotDEVELOPMENTAL STAGE: During flower initiation, expressed in the peripheral zone of the shoot apical meristem. Confined to the anlagen of successive flower buds yet to arise. Later expressed in abaxial and adaxial sepal primordia, but not in sepals. When sepals initiate, localized in the region interior to them. Within the gynoecium, detected in the initiating and developing medial regions, and then in the developing septum and stigma. SPT expression also occurs in sub-regions of developing ovules, and in the wall and dehiscence zone of the maturing fruit. As the petals develop, becomes restricted to the adaxial epidermis. In stamen expression increase in the vicinity of the archesporial cells and in cells undergoing divisions to produce sporogenous and secondary parietal cells of the anther locules. Expressed in the tapetum and microspore mother cells until the initiation of meiosis. Also detected in stomium and filaments. {ECO:0000269|PubMed:11245574}.
UniprotTISSUE SPECIFICITY: Expressed in lateral root caps, young leaves, stipules, maturing pith cells of the stem, differentiating vascular cells, shoot apical meristems and flowers. {ECO:0000269|PubMed:11245574}.
