The NO levels were increased in the WT under heat stress. (A) Change in NO level detected using DAF-FM DA staining in the WT with different heat stress times. (B) Changes in the NO fluorescence ratio in the WT strain. The values are the means ± SE of three independent experiments. Different letters indicate significant differences for the comparison of samples (P < 0.05 according to Duncan’s test).
