floral organ abscission vesicle-mediated transport obsolete vesicle-mediated transport involved in floral organ abscission https://github.com/geneontology/go-ontology/issues/29252 true membrane trafficking involved in floral organ shedding dph This term was obsoleted because it represents a GO-CAM model. GO:0060858 OBSOLETE. The directed movement of substances within a cell by a cellular process that begins with the formation of membrane-bounded vesicles in which the transported substances are enclosed or located in the vesicle membrane which are then targeted to, and fuse with, an acceptor membrane contributing to the shedding of a floral organ. biological_process 2009-08-12T03:48:54Z
