Expression of VvPR1 and VvSTS after transient overexpression of AtNPR1 and VvNPR1.1 in grapevine leaves. (A, B) Expression levels of VvPR1 (A) and VvSTS (B), in uninoculated leaves, 3 days after agro-infiltration. (C, D) Expression levels of VvPR1 (C) and VvSTS (D) in uninoculated and inoculated leaves. Leaves were infiltrated with Agrobacterium carrying the different constructs and expression of VvPR1 and VvSTS was analyzed 3 days later (grey bars). Three days after agroinfiltration, leaves were inoculated with P. viticola and expression of genes of interest was analyzed 2 days after inoculation (black bars). Fold induction indicates expression levels in agroinfiltrated leaves compared to the expression in non-inoculated water-infiltrated leaves, which is set to 1. Mean values and standard deviations were obtained from 2 duplicate experiments.
