Abstract The effects of the phytotoxin coronatine formed by pathovars of Pseudomonas syringae on coronatine sensitive cell cultures of Lycopersicon peruvianum and Lycopersicon esculentum were investigated. The studied parameters were ethylene release, activity of membrane‐bound ATPase and vitality using the TTC test. The cells of L. esculentum responded with an increase, the cells of L. peruvianum with a decrease of ethylene formation after application of different coronatine concentrations. These results indicate that the effect on ethylene release is not the primary effect of the toxin. The activity of membrane‐bound ATPase was not affected by coronatine.
