CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Tapetum of anthers. {ECO:0000269|PubMed:1627774}.
CC   -!- DEVELOPMENTAL STAGE: Found when sporogenous cells are in early meiosis.
CC       Disappears totally as the microspores go into interphase, when the
CC       tapetal cell layer degenerates. {ECO:0000269|PubMed:1627774}.
CC   -!- SIMILARITY: Belongs to the A9/FIL1 family. {ECO:0000305}.
