Vacuole (Potential)."	--NA--	CANVCHSERFSGGKCRGFRRRCFCTTHCMKSSMKMFAALLLVVMCLLANEMGGPLVVEARTCESQSHKFKGTCLSDTN	78	"Experimental evidence at transcript level"	8627.2	8621.04	9.01	--NA--	"FUNCTION:May play a protective role in flowers by protecting the reproductive organs from potential pathogen attack.TISSUE SPECIFICITY:Highest expression in flowers and to a lesser extent in leaves. Lower levels in hypocotyls. No expression in roots and cotyledons.DEVELOPMENTAL STAGE:Expressed progressively during flower development reaching the highest level in the mature fertilized flower stage.SIMILARITY:Belongs to the plant defensin family."
