Fig. 5From: Genome-wide identification and functional analysis of the ERF2 gene family in response to disease resistance against Stemphylium lycopersici in tomatoExpression of SA and JA, expression of related genes and predictive expression model. A SA (a) and JA (b) hormone levels in the ERF2-silenced plants. The data presented in (A) are the means ± SD from three independent experiments, and different letters above the columns indicate significant differences at the p < 0.05 level. B Silencing of ERF2 decreased the expression levels of the Pto and PR genes after infection with S. lycopersici. TRV::00, empty vector plants; TRV::ERF2, ERF2-silenced plants. The asterisks indicate significant differences in the expression levels between the silenced lines and the control lines (**p < 0.01; *p < 0.05, Student’s t-test).
