Hypocotyl length and AR-formation in dark-grown JA-mutant seedlings treated with IBA + Kin and MeJA. (a) Mean hypocotyl length (±SE) at 22 DAS of dde2–2, opr3 and coi1–16 mutants, and of their WTs (Col, Ws and Col-gl1, respectively), grown either in the absence of MeJA (0 μM MeJA) or with 0.01 μM or 0.1 μM MeJA. (b) Mean AR-density, i.e. mean ARP/AR number per cm of hypocotyl, (±SE) on the same seedlings as in (a). Significant differences between treatments within the same genotype, or between each mutant and its WT under the same treatment, at least at P < 0.05 level, are indicated by different letters. The same letter shows no statistical difference. Further statistical details are described on the text. N = 30 (first replicate)
