Phenotype of a promoterA9::5mARF17-GFP/WT plant. a A 35-day-old promoterA9::5mARF17-GFP (pA9::5mARF17-GFP/WT) plant. Bar = 2 cm. b Alexander’s staining of the anthers of a pA9::5mARF17-GFP/WT plant. Bar = 200 μm. c GFP signals were observed exclusively in the tapetal cells of pA9::5mARF17-GFP/WT plants. Bar = 50 μm. d Semi-thin sections of the anthers of a pA9::5mARF17-GFP/WT plant showing pollen development from anther stages 6–9. Bar = 20 μm. DMsp, degenerated microspore; MC, meiotic cell; Msp, microspore; T, tapetum; Tds, tetrads
