SP5G expression analysis conducted by qRT-PCR in tomato plants under different light treatments and DN conditions. a The expression of SP5G mRNA at 1, 2, and 3 days after the cessation of red (R) light night break (NB). b The diurnal expression of SP5G mRNA when tomato plants were treated by R light NB and red and far red (R + FR) light NB, respectively. c The expression of SP5G mRNA at 1, 2, and 3 days after cessation of far red (FR) light. d The diurnal expression of SP5G mRNA when tomato plants were treated with FR light and FR light was ended. All data are expressed as means ± SE of three independent pools of extracts. Three technical replicates were performed for each extract. Bars with different letters are significantly different at the P < 0.05 level according to Duncan’s multiple range test. White, black, red and blue bars at the bottom indicate light, dark red and far-red light periods, respectively
