Fig 9. Effect of Citrus Exocortis Viroid (CEVd) and Tomato Spotted Wilt Virus (TSWV) infections on levels of p-coumaroyltyramine (CT), feruloyltyramine (FT), caffeoylputrescine (CaP), and feruloylputrescine (FP) in Money Maker and NahG tomato leaves.

Plants were inoculated with either CEVd or TSWV and samples were collected at the indicated times (weeks post-inoculation, wpi) for both infected and mock-inoculated leaves, and then analyzed by HPLC/ESI-MS. Data correspond to the mean ± SD of three biological replicates of one representative experiment. The experiments were repeated at least 3 times.
