Contents of the phytohormones a) ABA and b) JA in Bur , L er and two near-isogenic lines. NIL9 contained Ler alleles in the variable region and NIL5 contained Bur alleles. a): Differences between mock- and V. longisporum-inoculated plants were significant (n = 6-7, p < 0.05). b) Asterisks refer to the significance level of differences between mock-inoculated and V. longisporum-treated plants within one genotype (t-test, n = 6). Mean contents of inoculated plants marked with different letters differed significantly at p < 0.05. Mean phytohormone contents of controls did not differ significantly (one-way ANOVA and post-hoc Tukey test). Vertical bars denote standard deviations. V43 = V. longisporum isolate 43.
