Abstract Effect of the Bacterial Phytotoxin Coronatine on Plant Cell Cultures The influence of the bacterial phytotoxin coronatine on cell cultures of Lycopersicon peruvianum and Chenopodium album was studied. It was detectable that the cell culture L. peruvianum more related to the host plant of the phytopathogenic bacteria reacts more sensitive to coronatine. Concentrations of 3.5 ng coronatme/ml culture liquid mduce reductions in growth and the TTC‐activity. In the case of the other used cell culture the critical amount of coronatine was higher than 7 ng/ml culture liquid. In further experiments the concentrations of free amino acids and proteins within the cell were followed. After 6–7 days of culture a slightly recovery of the cultures treated with coronatine was detectable.
