Abstract: Elicitors induce defense responses that resemble those triggered by pathogen attack, including the synthesis of phytoalexins and pathogen-related proteins, which are accumulated in the extracellular space. In this work we analyze the changes in the secretome of Vitis vinifera cv. Monastrell cell cultures. This refers to the secreted proteome obtained from cell suspension cultures, in response to treatment with cyclodextrins and methyl jasmonate, separately or in combination using label-free quantitative approaches. Of the proteins found, thirty-three did not show significant differences in response to the different treatments carried out, indicating that these proteins were expressed in a constitutive way in both control and elicited grapevine cell cultures. These proteins included pathogenesis-related proteins 4 and 5, class III peroxidases, NtPRp-27, chitinases and class IV endochitinases, among others. Moreover, eleven proteins were differentially expressed in the presence of cyclodextrins and/or methyl jasmonate: three different peroxidases, two pathogenesis related protein 1, LysM domain-containing GPI-anchored protein 1, glycerophosphoryl diester phosphodiesterase, reticulin oxidase, heparanase, β-1,3-glucanase and xyloglucan endotransglycosylase. Treatments with cyclodextrins reinforced the defensive arsenal and induced the accumulation of peroxidase V and xyloglucan endotransglycosylase. However, elicitation with methyl jasmonate decreased the levels of several proteins such as pathogenesis related protein 1, LysM domain-containing GPI-anchored protein 1, cationic peroxidase, and glycerophosphoryl diester phosphodiesterase, but increased the levels of new gene products such as heparanase, β-1,3 glucanase, reticulin oxidase, and peroxidase IV, all of which could be used as potential biomarkers in the grapevine defense responses.
