Fig. 6: The Arabidopsis gain-of-function mutant bzr1-1D shows delayed floral organ abscission.

a Photographs of the floral organ abscission process in Col and the bzr1-1D mutant. b BCECF signals of the floral organ AZ of Col and the bzr1-1D mutant. c pBS of the bzr1-1D mutant compared with that of Col (n = 30, bars = SD). d Floral organ abscission rate of Col and the bzr1-1D mutant under EBR or ACC treatment. e Ethylene production of Col and the bzr1-1D mutant under EBR or ACC treatment. f–g Expression levels of AtACS1 and AtACO4 in Col and the bzr1-1D mutant under EBR or ACC treatment. The SE was calculated from three replicates. Different letters indicate significant pairwise differences by Duncan’s test (p < 0.05).
