Source Description
UniProtEssential for tapetum development in anthers and microsporogenesis. May regulate the timing of tapetal programmed cell death (PCD) which is critical for pollen development. {ECO:0000269|PubMed:22086333}.
UniProtTranscription factor that binds to the DNA sequence 5'-CCAACC-3'. Regulates directly PME5, UND and GLOX1 (PubMed:21673079). Essential for tapetum development in anthers and microsporogenesis (PubMed:12848824, PubMed:21673079). Regulates the timing of tapetal programmed cell death (PCD) which is critical for pollen development. May act through the activation of UND, encoding an A1 aspartic protease (PubMed:21673079). Required for anther development by regulating tapetum development, callose dissolution and exine formation. Acts upstream of A6 and FAR2/MS2, two genes required for pollen exine formation (PubMed:17727613). Negatively regulates trichome endoreduplication and trichome branching (PubMed:12848824). {ECO:0000269|PubMed:12848824, ECO:0000269|PubMed:17727613, ECO:0000269|PubMed:21673079}.
