CC -!- FUNCTION: Transcription factor that binds to the DNA sequence 5'-
CC CCAACC-3'. Regulates directly PME5, UND and GLOX1
CC (PubMed:21673079). Essential for tapetum development in anthers
CC and microsporogenesis (PubMed:12848824, PubMed:21673079).
CC Regulates the timing of tapetal programmed cell death (PCD) which
CC is critical for pollen development. May act through the activation
CC of UND, encoding an A1 aspartic protease (PubMed:21673079).
CC Required for anther development by regulating tapetum development,
CC callose dissolution and exine formation. Acts upstream of A6 and
CC FAR2/MS2, two genes required for pollen exine formation
CC (PubMed:17727613). Negatively regulates trichome endoreduplication
CC and trichome branching (PubMed:12848824).
CC {ECO:0000269|PubMed:12848824, ECO:0000269|PubMed:17727613,
CC ECO:0000269|PubMed:21673079}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-
CC ProRule:PRU00625, ECO:0000269|PubMed:17727613}.
CC -!- TISSUE SPECIFICITY: Expressed in the tapetum and middle layer of
CC developing anthers (PubMed:10353220). Expressed in trichomes
CC (PubMed:12848824). {ECO:0000269|PubMed:10353220,
CC ECO:0000269|PubMed:12848824}.
CC -!- DEVELOPMENTAL STAGE: During anther development, expressed from
CC stage 4 to stage 6 in microsporocytes and tapetal cells. At the
CC tetrad stage, expressed predominantly in tapetal cells. During
CC microgametogenesis, expression decreases radically in the tapetum
CC and microspores. {ECO:0000269|PubMed:21957980}.
CC -!- DISRUPTION PHENOTYPE: Male sterility due to distorted pollen
CC grains lacking reticulate exine on their surface.
CC {ECO:0000269|PubMed:17727613}.
CC -!- MISCELLANEOUS: Plants silencing MYB80 have the majority of pollen
CC grains distorted in shape with reduced or no cytoplasmic content,
CC display early tapetal degeneration with large opaque bodies in the
CC tapetal cytoplasm, and trichomes on cauline and rosette leaves
CC contain increased nuclear DNA content and produces additional
CC branches. {ECO:0000269|PubMed:12848824}.
CC -!- SIMILARITY: Contains 2 HTH myb-type DNA-binding domains.
CC {ECO:0000255|PROSITE-ProRule:PRU00625}.
