Fig. 6: Relative expression (indicated as normalized relative expression) of some genes coding for differentially abundant proteins in the two Tuscan varieties.

Error bars refer to the standard deviation (n = 4). Different letters represent the statistical significance (p < 0.05) present among the groups of data obtained. If a letter is shared, the difference is not significant. A one-way ANOVA followed by Tukey’s post-hoc test was performed on genes showing homogeneity and normal distribution; for the others, a Kruskal-Wallis test followed by Dunn’s post-hoc test was used. The statistical parameters are: BAS1 X²(5) = 2.98, p-value = 0.702; GST F(5,17) = 4.16, p-value = 0.012; HSP17 F(5,17) = 7.28, p-value = 0.001; PPO F(5,17) = 9.96, p-value = 0.000; SRC2 F(5,17) = 12.88, p-value = 0.000; XTH31 F(5,17) = 34.95, p-value = 0.000; XTH6 F(5,17) = 0.3449, p-value = 0.846; SOD F(5,17) = 6.33, p-value = 0.002; CPN20 F(5,17) = 7.07, p-value = 0.001; 70HS X²(5) = 1.067, p-value = 0.957; 70HS2 F(5,17) = 9.14, p-value = 0.000; VI1 F(5,17) = 1.55, p-value = 0.225; XYL1 F(5,17) = 1.300, p-value = 0.310; BGL X²(5) = 14.27, p-value = 0.014; RBG2 X²(5) = 4.083, p-value = 0.537; LTP F(5,17) = 8.73, p-value = 0.000; NTR F(5,17) = 4.51, p-value = 0.008; UGP2 F(5,17) = 2.49, p-value = 0.072; DHAR2 F(5,17) = 1.539, p-value = 0.230
