Fig. 6From: Phytochrome B1-dependent control of SP5G transcription is the basis of the night break and red to far-red light ratio effects in tomato floweringPhytochrome B1 is responsible for the expression of SP5G and influences the flowering of tomato plants by night break (NB) and different red-to-far-red light (R:FR) treatments. The leaf stage at flowering in tomato for (a) WT plants as well as (c) phyA, (e) phyB1, and (g) phyB2 mutants treated by NB and different R:FR treatments. Data are mean ± SE of 10 plants. Bars with different letters are significantly different at the P < 0.05 significance level according to Duncan’s multiple range test. The diurnal expression of SP5G in tomato for (b) WT plants as well as (d) phyA, (f) phyB1, and (h) phyB2 mutants treated by NB and different R: FR treatments. Data are expressed as means ± SE of three independent pools of extracts. Three technical replicates were performed for each extract. White, black, red and blue bars at the bottom indicate light, dark red and far-red light periods, respectivelyBack to article page
