AB  - Notwithstanding significant interest towards study of adenylate cyclase plant signal system, there is still no complete picture of functioning and regulation mechanisms of this signal system in plants under biotic stress. With this in view, our study was aimed at identification of various forms of adenylate cyclase (transmembrane and “soluble”) in the nucleus and chloroplasts of potato cells and modulation of their activity under the impact of exopolysaсcharides of potato ring rot pathogen. The investigations conducted allowed to conclude that two forms of adenylate cyclase function in nuclei and chloroplasts of potato plants: transmembrane and “soluble”. Activity of these forms of the enzyme extracted from plant cells of the two potato varieties contrasted by resistance to potato ring rot pathogen Clavibacter michiganensis subsp. sepedonicus, changed in the reverse manner with the mediated impact of exopolysaсcharides secreted by virulent and mucinous strain of bacterial pathogen: in the plants of resistant сultivar it increased, in the plants of sensitive сultivar it was oppressed. It was concluded that activity of both forms of adenylate cyclase directly depended on the degree of resistance of a particular potato variety to given pathogen.
