The slow response of LFP floral buds to various warm temperature regimes and the expression profiles of peach thermal-responsive flower regulator genes. (a) The fully chilled floral buds of JB (800 CH) and LFP (1,000 CH) were transferred to a growth chamber with temperatures set at 10°C, 15°C, and 20°C for 6, 9, 13, 16 and 21 days (Day 6, 9, 13, 16 and 21), respectively. (b-g) Expression profiles of genes PRUPE_3G179800/PIF4 (b), PRUPE_6G071400/LUX (c), PRUPE_1G416000/ELF3 (d), PRUPE_2G249800/ELF4 (e), PRUPE_6G302500/PhyA (f) and PRUPE_1G117000/PhyB (g).
