CC   -!- FUNCTION: May be involved in protecting plant tissues from pathogen
CC       infection. {ECO:0000303|PubMed:11847241}.
CC   -!- SUBCELLULAR LOCATION: Secreted, cell wall
CC       {ECO:0000250|UniProtKB:P85494}.
CC   -!- TISSUE SPECIFICITY: Preferentially expressed in the tissue surrounding
CC       the abscission zone of fruitlets. {ECO:0000269|PubMed:11847241}.
CC   -!- DEVELOPMENTAL STAGE: Expressed during the late stages of both fruit
CC       ripening and leaf senescence. {ECO:0000269|PubMed:11847241}.
CC   -!- INDUCTION: Up-regulated in both the abscission zone and surrounding
CC       tissues following treatment with propylene and after wounding due to
CC       embryoctomy. {ECO:0000269|PubMed:11847241}.
