Effects of selected inhibitors on morphology and growth of B. distachyon roots. Top: Bright-field images with control root on the left and inhibitor-treated on the right. (a,b) 100 nM oryzalin for 48 h; (c,d) 0.5 µM DCB for 48 h; and (e,f) 250 nM latrunculin for 19 h. Scale bars = 0.3 mm (bar in b is for a and b; bar in e is for c–f). Bottom: Dose-response curves. Symbols plot mean ± SE for a representative experiment with 8 to 12 seedlings per datum. Open circles plot elongation, closed squares plot diameter.
