Production of reactive oxygen species (ROS) in tomato leaf disks after treatment with Cladosporium fulvum. Tomato leaf disks were treated with C. fulvum at the concentration of 1×10⁶ conidia/ml and water as control. ROS production was measured using the chemiluminescence of luminol and photon counts were expressed as relative luminescence units (RLUs). The X-axis indicates time, and the instrument measures one value every 10 s, for a total of 160 values, Y-axis indicates the level of ROS accumulation by relative luminescence units. The results are presented as means ± SE of three biological and three technical replicates.
