Abstract To identify and characterize genes involved in reproductive tissue abscission in Brassica oleracea, the transcript data of pollinated pistil was analyzed. A differentially expressed gene, named BoFAZ1(FLOWER ABSCISSION ZONE1) was identified, which contains one exon and encompass a 139aa. Furthermore, a T-DNA insertion mutant (SALK_302_G01) (faz1 mutant) was obtained from Arabidopsis thaliana mutant library. Floral organ shedding from mutants was delayed and a V-shaped structure in the boundary region between the stalk and torus of the sepal abscission zone was obtained in faz1 mutant. The cell density of this structure was lower than that of the corresponding region in the… More >
