Functional Description ? help Back to Top
Source Description
UniProtTranscription factor required for sugar partitioning from leaves to anthers during male reproductive development. Required for the production of functional pollen grains. Binds to the promoter of the anther-specific sugar transporter MST8 and regulates its expression. Regulates the expression of genes involved in sugar partitioning in flower, such as the sugar transporter SUT3, the invertase INV4, the UDP-glucose pyrophosphorylase UGP2 and the starch synthase WAXY. {ECO:0000269|PubMed:20305120}.
UniProtTranscription factor that confers sensitivity to abscisic acid (ABA) and salt, but tolerance to drought (PubMed:21399993). Regulates secondary cell wall (SCW) biosynthesis, especially in interfascicular and xylary fibers (PubMed:18952777, PubMed:23781226). {ECO:0000269|PubMed:18952777, ECO:0000269|PubMed:21399993, ECO:0000269|PubMed:23781226}.

Source Description
UniProtINDUCTION: By abscisic acid (PubMed:16463103, PubMed:21399993). Accumulates in response to salt (PubMed:21399993). Triggered by MYB46 and MYB83 in the regulation of secondary cell wall biosynthesis (PubMed:19674407, PubMed:22197883). {ECO:0000269|PubMed:16463103, ECO:0000269|PubMed:19674407, ECO:0000269|PubMed:21399993, ECO:0000269|PubMed:22197883}.
