Proportions (number of plants infected/total number of plants tested) followed by the same letter within each column indicate no significant differences (P < 0.05) according to pairwise comparisons using a chi-square test or a Fisher's exact test when expected values were lower than 5. The same letters in parentheses within each column indicate no significant differences (P < 0.05) on the basis of a multiple-pairwise-comparison Tamhane T2 test. WT, wild type.
