HDA9 and ABI4 regulate CYP707A1 and CYP707A2 expression to dehydration. (A, B) Quantitative RT-PCR analyses of CYP707A1 (A) and CYP707A2 (B) in WT, hda9-1, abi4, and hda9-1abi4 after dehydration stress treatment. Total RNA was extracted from 10-d-old seedlings treated with dehydration stress for indicated times. Expression of TUBULIN8 was used for normalization. Bars represent mean ± SD of three biological replicates with three technical replicates each. Asterisks represent significant differences from the WT (*, 0.01 < p-value ≤ 0.05; **, p-value < 0.01; Student's t-test).
