Our aim was to investigate the ability of cadmium to induce programmed cell death in tomato suspension cells and to determine the involvement of proteolysis, oxidative stress and ethylene. Tomato suspension cells were exposed to treatments with CdSO
Key words: Cadmium, Ethylene, Lycopersicon esculentum Mill, Oxidative stress, Proteolysis.
