Inhibitory effects of CL derivatives on increased lateral inflorescences of Arabidopsis max mutants. Each 10 μM solution of CL, 19-hydroxy-CL, CLA, and MeCLA (all racemic mixtures) was applied onto the basal region of the primary inflorescences of max1, max4, and max2 every second day for 2 wk, and then the number of lateral inflorescences from rosette leaves was counted. The 0.5% (vol/vol) acetonitrile solution without authentic sample was used as a mock treatment. Values are mean ± SEM (n = 15). The number of lateral inflorescence was 1.4 ± 0.3 in WT treated with the mock solution. Different letters indicate significant differences tested by the Holm-Sidak method under ANOVA (P < 0.05).
