Figure 5. — Treatment with a BR Inhibitor Suppresses Bristle Formation in S. viridis Panicles.

(A) Compared with untreated wild-type (left) and bsl1-1 mutant (middle) plants, plant height was reduced after treating A10.1 wild-type seedlings with PCZ (right). Bar = 5 cm.

(B) Compared with the untreated control (left), treatment with PCZ suppressed bristle production in A10.1 wild-type panicles (right) and phenocopied untreated bsl1-1 mutant panicles (middle). Bar = 1 cm.

(C) to (E) Scanning electron microscopy analysis of inflorescences from PCZ-treated wild-type plants showed that by 17 DAS (C), there was no sign of bristle differentiation, but spikelets (white arrows) developed normally. At 19 DAS (D), ectopic development of rudimentary spikelets (white arrows) was observed as in bsl1-1 and a few randomly placed bristles (yellow arrow) were observed. Development of both upper (white asterisk) and lower (red asterisk) florets was observed in the PCZ-treated inflorescences (E). Bars = 200 μm in (C) and (D) and 50 μm in (E).
