A comparative analysis of differentially expressed proteins in a susceptible grapevine ( Vitis vinifera ‘Cabernet Sauvignon’) during the infection of Erysiphe necator , the causal pathogen of grapevine powdery mildew (PM), was conducted using iTRAQ. The quantitative labeling analysis revealed 63 proteins that significantly changed in abundance at 24, 36, 48, and 72 h post inoculation with powdery mildew conidiospores. The functional classification of the PM‐responsive proteins showed that they are involved in photosynthesis, metabolism, disease/defense, protein destination, and protein synthesis. A number of the proteins induced in grapevine in response to E. necator are associated with the plant defense response, suggesting that PM‐susceptible Cabernet Sauvignon is able to initiate a basal defense but unable to restrict fungal growth or slow down disease progression.
