Ethylene biosynthesis was measured as previously described (Leibman-Markus et al., 2017). Leaf disks 0.9 cm in diameter were taken from transiently expressing plants 40 h post-infection. Every five disks were sealed in a 10 mL flask containing 1 ml assay medium (with or without 1 μg/mL EIX) for 4 h at room temperature. Ethylene production was measured by gas chromatography using Varian 3350 equipment.
