A schematic representation of the experimental design based on two iTRAQ 8-plex experiments. a Systemic TMV or TMV 24A + UPD infection in leaves was analysed by western blot detection of viral coat protein, at 1, 2 and 3 days post-inoculation (dpi). b Total protein samples were collected at 2 and 3 dpi and processed immediately for iTRAQ labelling
