C3H15_ARATH-2 C3H15_ARATH | function | Functions probably as a transcriptional factor that activates genes involved in secondary cell wall biosynthesis (PubMed:25228083, PubMed:25732536). Functions redudantly with C3H14 to regulate secondary cell wall formation (PubMed:25732536). C3H14 and C3H15 have overlapping roles in the regulation of secondary cell wall formation and anther development (PubMed:25732536). C3H14 may contribute more to secondary cell wall thickening while C3H15 could be more important in anther development (PubMed:25732536). May regulate at both the transcriptional and post-transcriptional levels the expression of many genes involved in various biological processes, particularly those associated with cell wall metabolism and pollen development (PubMed:25732536). Involved in the regulation of callose metabolism in male meiocytes, in integrity of newly formed microspores, and promotes male fertility (PubMed:24567187). May be involved in the regulation of the callose synthesis genes CALS5 and CALS12, the potential degradation of callose walls-related genes A6 and MYB80, as well as other putative beta-1,3-glucanase genes (PubMed:24567187). Negatively regulates cell elongation by inhibiting brassinosteroid (BR) signaling (PubMed:35139225). Functions downstream of the BRI1 receptor as a negative regulator in the BR pathway (PubMed:35139225). |
C3H15_ARATH-2 C3H15_ARATH | subcellular location | Localizes in cytoplasm in the absence of brassinosteroids (BRs). Upon BR perception, C3H15 accumulates in the nucleus. |
C3H15_ARATH-2 C3H15_ARATH | tissue specificity | Highly expressed in secondary cell wall-forming tissues and the xylem cells of roots (PubMed:25228083). Expressed predominantly in inflorescence stems, flowers and siliques (PubMed:25732536). Highly expressed in the basal portion of stems, where cells are undergoing secondary cell wall thickening (PubMed:25732536). Highly expressed in meiocytes and tapetum from anthers (PubMed:24567187). |
