SA and ETH regulate the expression of PpMAPK3-L, PpMAPK7-L, PpMAPK10-L and PpMAPK16-L. The X-axis in the figure represents samples treated with 0, 0.002, 0.02, 0.2, and 2 mM SA for 12 h, and with 1 µL/L ETH for 3, 6, 12, 24, 36, and 48 h in the fruit flesh of ‘Whangkeumbae’. The Y-axis indicates the relative expression levels of the PpMAPK genes. Data are expressed as percentages relative to PpUBI expression levels. The results shown are derived from three independent biological replicates, with data presented as means ± SD and error bars representing the variability of the expression. Statistical significance is indicated by “*” (P < 0.05), and highly significant differences are denoted by “**” (P < 0.01)
