THE CHANGE OF KINETIK PARAMETERS OF THE WEAKASSOCIATED WITH WALL CELL PEROXIDASE IN THE SUSPENSION CULTURE OF POTATO CELLS IN THE BEGINNING OF INFECTION
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2006, Vol 2, Issue 1
Abstract
The change in kinetic parameters of extracellular peroxidase of suspension cells of resistant potato variety (Lugovskoi) and sensitive variety (Luk,ynovskii) in the initial period of infection by 5369 Clavibacter michiganensis subsp. sepedonicus (Spieck. et Kotth.) Skapt et Burkh. pathogen was examined. Extracellular peroxidases of resistant and sensitive potato variety without pathogens were shown to be concurrently inhibited. At the beginning of infection enzyme activity was extremely increased due to enhanced affinity to substrate as a result of reducing of competitive inhibiting. In increasing enzyme activity is sensitive potato variant evidently caused by other mechanism.
