  Fungi of different species of the Alternaria genus isolated from potato or tomato plants in several Russian regions excreted proteolytic enzymes during the growth in the medium containing thermostable proteins of pea and carrot. The growing of fungi in such medium can be considered as a model system for studying the infection process. It has been shown increased production of proteolytic enzymes that included serine proteases belonging to the subtilisin and trypsin families. In most isolates, the proteolytic enzymes production has been observed during the exponential phase of growth. The data obtained demonstrated that the exoproteinase activity depended on the natures of both the isolate and its host plant, but it was defined by the isolate's genotype predominantly. The data also clearly demonstrated a phenomenon of exceeding of .. View More»
