Expression level of auxin signaling-related (a) or gibberellin signaling-related genes (b) under heat stress treated with 4-CPA or EtOH. The expression level of auxin signaling-related genes, such as TAR2a, TAR2b, ARF5, and ARF7, were measured. The expression level of gibberellin signaling-related genes, such as GA20OX1, GA3OX2, GA2OX1, GA2OX5, and GID1, were also investigated. Statistical analysis was performed to determine significant differences compared to the control at p < 0.05 (*) and at p < 0.01 (**) (n ≥ 3).
