Ec, 1 DAI with Erysiphe cichoracearum; Bgh, 1 DAI with Blumeria graminis f. sp hordei; Unin, uninoculated. Based on the analysis of variance with a Benjamini and Hochberg multiple text correction, the P values for these genes were <0.0008 for the factor genotype and for the factor infection. Values shown indicate average fold induction relative to uninoculated Col-0 (n = 4).
