Fig. 1From: Indole-3-butyric acid promotes adventitious rooting in Arabidopsis thaliana thin cell layers by conversion into indole-3-acetic acid and stimulation of anthranilate synthase activityAdventitious rooting in Arabidopsis thaliana TCLs under different hormonal treatments. a Percentage of TCLs, Col-0 ecotype, either at the initial stage or with macroscopic callus and ARs, after 15 days of culture without hormones (HF) or with IBA (10 μM) + Kin (0.1 μM), IBA (10 μM), IAA (10 μM) or Kin (0.1 μM). b Productivity of AR-forming TCLs evaluated as mean number (±SE) of ARs per TCL under either IBA (10 μM) + Kin (0.1 μM), or IBA (10 μM), or IAA (10 μM). a,d P < 0.01 difference with respect to the other treatments within the same developmental stage. b,c, P < 0.01 difference with respect to IBA + Kin and IBA within the same developmental stage. e, P < 0.01 difference with respect to IAA. f, P < 0.001 difference with respect to IBA + Kin. Columns with no letter or the same letter within the same developmental stage are not significantly different. N = 100Back to article page
