one of the most efficient mechanisms by which plants protect themselves from invading virusesis the specific rna-dependent silencing pathway termed post-transcriptional gene silencing(ptgs). in this mechanism, resistance to a virus is engineered through the expression of asegment of the virus genomein transgenic plants. potato virusy (pvy) is one of the mostdamaging viruses of potato, infecting...

Aged plants are more difficult to infect than young plantlets. This modification of susceptibility is described as mature plant resistance (MPR). For potato virus Y (PVY), MPR known lead low infection rates inoculated at the postflowering stage and a decrease in number infected daughter tubers. However, impact inoculation date on capacity PVY accumulate tubers has not been studied so far. Field...

From 17 November to 27 December 2022, extremely cold snowstorms frequently swept across North America and Eurasia. Diagnostic analysis reveals that these extreme events were closely related the establishment of blocking circulations. Alaska Blocking (AB) subsequent Ural (UB) episodes are linked phase transition Atlantic Oscillation (NAO) represent main atmospheric regimes in Northern Hemisphere...

Goal. Molecular identification of carriers the potato virus Y (PVY) resistance genes Rychc and Ryadg among lines Polissia Research Station Institute Potato Growing National Academy Agrarian Sciences Ukraine.
 Methods. Seventy produced by were studied. We used molecular markers indicating presence specific Ry in genome lines. Those are responsible for plant’s response to pathogen extreme (E...
