An LsKAI2b transgene confers strong KAR₁ responses to Arabidopsis seedlings. Hypocotyl length of 5-day-old A. thaliana seedlings grown under red light on 0.5× MS media supplemented with 0.1% (v/v) acetone or 1-µM KAR₁, KAR₂, or rac-GR24. n = 20 seedlings. Box plots indicate median and quartiles with Tukey’s whiskers. Gray dots indicate outlier data beyond Tukey’s whiskers. ^*P < 0.01, Dunnett’s multiple comparisons test, treatment versus mock comparison within each line. ^#P < 0.01, Dunnett’s multiple comparisons test, comparison to d14 kai2, mock-treated samples only.
