^*The SNP (5 μM), cPTIO (100 μM) and NS-2028 (20 μM) were added to the culture 30 min before the red light treatment. The intensity of red light (627 nm) was 200 lx. The culture was maintained in a 150 mL flask containing 50 mL medium at 150 r/min and 28 ℃ for 8 days. The treatments consisted of triplicate independent repeats (ten flasks per replicate, ^*p < 0.05, ^**p < 0.01 vs. control; ^#p < 0.05, ^##p < 0.01 vs. red light treatment)
