Loss of EFR kinase activity does not compromise immune responses. (A) Fluorometric measurement of β-GUS activity in leaves of 3-wk-old plants 5 d after infiltration of leaves with Agrobacterium containing the pBIN19g:GUS plasmid. Mean with SEM and individual data points are shown. Means with like letter designations are not statistically different (Brown–Forsythe ANOVA, P = 0.000338, n = 5 or 6 plants, Dunnett’s multiple comparisons). The experiment was repeated three times with similar results. (B) Growth of Pto DC3000 2 d after infiltration in leaves pretreated with either mock or 1 µM elf18 for 24 h. Mean with SEM and individual data points (n = 23 or 24 plants) from three pooled independent experiments are shown. P values are derived from the comparison between elf18 pretreatment and mock, separately for each genotype as described in Experimental Procedures. Asterisk indicates a statistical difference between mock and elf18-treated leaves within each genotype.
