Levels of histone H3K9ac, H3K27ac and H4K5ac under NaCl and drought treatments. a, c Western blot showing the H3K9ac, H3K27ac and H4K5ac status in kenaf roots treated with NaCl and PEG solution. 7-day-old seedlings were treated under 0, 100, 200 mM NaCl, and 0%, 10%, 20% PEG6000 conditions for 7 days, respectively, and the roots were sampled for histone proteins extraction. b, d Quantification of western blot results. Signal intensities were measured using the ImageJ software and normalized to the loaded amount of H3. Values are expressed as fold change over control treatment. Shown is the mean ± SEM of three independent experiments. P value < 0.05, Student’s t-test
