Epigenetic factors indicating individual plant sensitivity to phytopathogens

Kravets .., Sokolova D.A.

 




SUMMARY. Two varieties of winter wheat Podolyanka and Favorytka of 20132017 harvests were studied for the connection of sensitivity to the phytopathogens and the dynamics of its development, considering the difference in the epigenome of plants, which is estimated by the DNA methylation profiles. It was demonstrated that rapidly germinating seedlings of the Podolyanka variety, in contrast to slowly germinating seedlings, had high disease resistance. The plants of Favorytka wheat did not demonstrate this difference. The estimation of changes in the epigenetic distance of the investigated varieties in terms of years demonstrated steadily high values of this index for Podolyanka variety and steadily low ones for Favorytka. The connection between epigenetic differences of plants and their individual sensitivity to phytopathogens, as well as the connection between epigenetic polymorphism, notable for the variety, and the diversity of strategies of non-specific stability and biodiversity of monofields of agricultural crops were discussed.

Key words: DNA methylation, Epigenetic polymorphism, phytopatogens, plants immunity
