Expression -- Description ? help Back to Top
Source	Description
Uniprot	DEVELOPMENTAL STAGE: During anther development, first confined to meiocytes, tapetal and middle layer cells. At the microspore stage, mainly expressed in the tapetum and microspores. Later observed in developing pollen grains. {ECO:0000269\|PubMed:18397379, ECO:0000269\|PubMed:21957980}.
Uniprot	TISSUE SPECIFICITY: Inflorescences-specific (PubMed:18397379). Accumulates in anthers, especially in tapetum and meiocytes/microsporocytes and microspores during anther development (PubMed:17666023, PubMed:18397379). {ECO:0000269\|PubMed:17666023, ECO:0000269\|PubMed:18397379}.

Functional Description ? help Back to Top
Source	Description
UniProt	Required for anther development and early tapetal function during microspore maturation (PubMed:18397379, PubMed:21957980). Regulates callose dissolution required for microspores release from the tetrads (PubMed:18397379). {ECO:0000269\|PubMed:18397379, ECO:0000269\|PubMed:21957980}.
