Source	Description
UniProt	Transcription 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}.
