Function

TCP15_ARATH Transcription factor involved the regulation of plant development. Together with TCP14, modulates plant stature by promoting cell division in young internodes. Represses cell proliferation in developing leaf blade and specific floral tissues (PubMed:21668538). Together with TCP15, acts downstream of gibberellin (GA), and the stratification pathways that promote seed germination. Involved in the control of cell proliferation at the root apical meristem (RAM) by regulating the activity of CYCB1-1 (PubMed:25655823). Acts together with SPY to promote cytokinin responses that affect leaf shape and trichome development in flowers (PubMed:22267487). Involved in gynoecium and silique development. Modulates the development of the different tissues of the gynoecium through its participation in auxin and cytokinin responses. Modulates the expression of the cytokinin-responsive genes ARR7 and ARR15. May repress the expression of the auxin biosynthetic genes YUC1 and YUC4 (PubMed:26303297). Acts as negative regulator of anthocyanin accumulation under high light conditions. Modulates the expression of transcription factors involved in the induction of anthocyanin biosynthesis genes (PubMed:26574599). Transcription factor involved in the regulation of endoreduplication. Represses endoreduplication by activating the gene expression of the key cell-cycle regulators RBR1 and CYCA2-3 (PubMed:25757472). Regulates the expression of the defense gene pathogenesis-related protein 2 (PR2) in antagonism to SRFR1, a negative regulator of effector-triggered immunity (PubMed:24689742).^{[1] [2] [3] [4] [5] [6] [7]}
