Figure 1. The LRR and fic domains of XopAC are required for XopAC-triggered immunity in Arabidopsis ecotype Col-0.
A boxplot representation of pathogenicity of wild-type Xcc strain 8004 and xopAC mutants (∆xopAC, ∆LRR, ∆fic, xopAC-H469A) complemented or not with pCZ917-xopACA (+xopAC) is shown: middle bar = median; box limit = upper and lower quartile; extremes = Min and Max values. Bacteria were inoculated by piercing the leaf central vein and infection symptoms were scored 7 days post-inoculation. Disease index indicates: 0-1 no symptoms; 1-2 weak chlorosis, 2-3 strong chlorosis; 3-4 necrosis. N=3. Each time, at least 4 plants were inoculated on at least 3 leaves. Statistical groups were determined using a Tukey HSD test (P<0.001) and are indicated by a letter.
