The resistance in potato cultivars against late blight caused by Phytophthora infestans is classified into vertical and horizontal. Several metabolites associated with resistance have been detected: phytoalexins such as rishitin, phytuberin, lubimin, solavetivone etc. Metabolite profiling is a novel technology for the discrimination of quantitative resistance in plants against pathogen stress. Metabolite profiles based on GC/MS analysis have been used to discriminate resistance in wheat against Fusarium graminearum.
