Expression of genes, encoded defense proteins, in potato plants infected with the cyst-forming nematode Globodera rostochiensis (Wollenweber 1923) Behrens, 1975 and modulation of their activity during short-term exposure to low temperatures

The expression of the principal genes providing an immune response in the roots of potato plants resistant and susceptible to the cyst nematode Globodera rostochiensis is investigated under conditions of infestation and with frequent variations in temperature. Differences in the immune status of res...

Description
Summary:The expression of the principal genes providing an immune response in the roots of potato plants resistant and susceptible to the cyst nematode Globodera rostochiensis is investigated under conditions of infestation and with frequent variations in temperature. Differences in the immune status of resistant and susceptible potato cultivars are revealed in the level of expression of R -genes ( H1 and Gro1-4 ), gene PAL , and defense genes of the PR-family ( PR1 , PR2 , PR3 , PR6 ). Varying the temperature changes the activity of transcriptome of susceptible plants towards activation of expression of R -genes, gene PAL , and defense genes; interactions between the plant and parasite are displaced towards induction of host resistance.
