Fig 11. Time course of ethylene production in NahG tomato leaves infected with Citrus Exocortis Viroid (CEVd) or Tomato Spotted Wilt Virus (TSWV) and their corresponding controls.

Samples were collected at the indicated times (weeks post-inoculation, wpi) for both mock-inoculated (Mock) and infected (Inf) plants, and ethylene was measured with a gas chromatograph fitted with a flame ionization detector (FID). Data correspond to the mean ± SD of three biological replicates of one representative experiment. The experiments were repeated at least 3 times.
