Functional Description ? help Back to Top
Source	Description
UniProt	Probable transcription factor that regulates lignified secondary cell wall thickening of the anther endocethium, which is necessary for anther dehiscence (PubMed:12753590, PubMed:17147638, PubMed:17329564). May play a role in specifying early endothecial cell development by regulating a number of genes linked to secondary thickening such as NST1 and NST2. Acts upstream of the lignin biosynthesis pathway (PubMed:17329564). {ECO:0000269\|PubMed:12753590, ECO:0000269\|PubMed:17147638, ECO:0000269\|PubMed:17329564}.
