CC -!- FUNCTION: Involved in self-incompatibility.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in microspores and in young and mature
CC anthers. {ECO:0000269|PubMed:11251101}.
CC -!- MISCELLANEOUS: The two genes are located within a perfect direct repeat
CC and probably exhibit identical expression patterns.
CC -!- SIMILARITY: Belongs to the DEFL family. {ECO:0000305}.
