Virus-induced changes on the level of process analysis are shown for primary metabolism- related processes (photosynthesis, major and minor sugar metabolism and glycolysis). Results of Gene set enrichment analysis using MapMan ontology at 1, 3, 4, 5 and 7 dpi are presented in potato cv. Désirée (NT) and NahG-Désirée (NahG). Only statistically significant (FDR p-value <0.10) enriched sets of genes are marked as induced (+) or repressed (-) process. dpi – days post inoculation, Process description – according to MapMan gene annotation. No of genes in BIN – number of all genes assigned to the BIN. Blanks denote that a current process was not statistically significantly enriched at a corresponding dpi. Visualization of these results in primary metabolism pathways is presented in Additional file 5
