Fig. S2. TAR in individual F1 and F2 populations from Pst-treated parents in matched environments. (a) Pst-elicited TAR against Pst in F1 plants at 3 dpi. See legend of Fig. 3a for details. Boxplots show the interquartile range (IQR; box) ± 1.5xIQR (whiskers), including median (horizonal line) and replication units (dots). Data represent 10Log-transformed bacterial titres (Log cfu cm-2; n=10-12) in leaves of single plants within individual F1 populations. P-values indicate statistical significance of parent treatment by Welch ANOVA of pooled F1 populations from similarly treated parents, and nested ANOVA with individual F1 population as random factor, respectively. Different letters indicate statistically significant differences between pooled F1 populations from similarly treated parents (Welch ANOVA + Games-Howell post-hoc test; α=0.05). (b) Pst-elicited TAR against Hpa in F1 plants at 6 dpi. See legend of Fig. 3b for details. Stacked bars show leaf frequency distributions across Hpa resistance classes within individual F1 populations (n=70-250). P-value indicates statistical significance of the parent treatment (Fisher’s exact test). Different letters indicate statistically significant differences between pooled F1 populations from similarly treated parents (pairwise Fisher’s exact tests + Bonferroni FDR, α=0.05). (c) Pst-elicited TAR against Hpa in F2 plants at 6 dpi after one stress-free F1 generation. See legend of Fig. 3c for details. Stacked bars show leaf frequency distributions across Hpa resistance classes within individual F2 populations (n=55-100). P-value indicates statistical significance of parent treatment (Fisher’s exact tests). Different letters indicate statistically significant differences between pooled F2 populations from a common parental ancestor (pairwise Fisher’s exact tests + Bonferroni FDR; α=0.05).
