Perner, B. (Jena Univ. (Germany). Biological Faculty) | Schmauder, H.-P.
The effect of the phytotoxin coronatine, formed by pathovars of Pseudomonas syringae, on the plant cell cultures of Lycopersicon peruvianum, Lycopersicon esculentum, Chenopodium album and Solanum tuberosum was investigated. The parameters studied were growth, triphenyltetrazolium chloride activity (test for reductase), cell protein content and activities of polyphenol oxidase and peroxidase, both within the cells and in the culture liquid. The cultures of Lycopersicon peruvianum and Lycopersicon esculentum cultures were more sensitive than Chenopodium album and Solanum tuberosum. The more resistant cultures possess a high level of extracellular polyphenol oxidase
