From: Fine regulation of ARF17 for anther development and pollen formation
PromoterARF17::5mARF17 plants show complete male sterility. a-c Alexander’s staining shows mature pollen in the anthers of a WT (a), a promoterARF17::5mARF17 (5mARF17/WT) plant (b) and an arf17 mutant (c). Bars = 50 μm. (d) Semi-thin sections of the anthers of a 5mARF17/WT plant. Bar = 20 μm. (e) TEM showing the microspore structures of WT, 5mARF17 and arf17 mutant plants at anther stage 8. Bar = 5 μm. DMsp, degenerated microspore; MC, meiotic cell; Msp, microspore; T, tapetum; Tds, tetrads
