Hypersensitive response (HR)-conferred resistance to viral infection restricts the virus spread and is accompanied by the induction of cell death, manifested as the formation of necrotic lesions. While it is known that salicylic acid is the key component in the orchestration of the events restricting viral spread in HR, the exact function of the cell death in resistance is still unknown. We sho...

BACKGROUND Mating behaviors in simple invertebrate model organisms represent tractable paradigms for understanding the neural bases of sex-specific behaviors, decision-making and sensorimotor integration. However, there are few examples where such neural circuits have been defined at high resolution or interrogated. METHODOLOGY/PRINCIPAL FINDINGS Here we exploit the simplicity of the nematode...

By combining high-throughput sequencing (HTS) with experimental evolution, we can observe the within-host dynamics of pathogen variants of biomedical or ecological interest. We studied the evolutionary dynamics of five variants of Potato virus Y (PVY) in 15 doubled-haploid lines of pepper. All plants were inoculated with the same mixture of virus variants and variant frequencies were determined...

Abstract Testing for potato viruses is globally very important to prevent a critical shortage of supply. In most countries, testing obligated by law. Germany, seed potatoes are monitored six viruses: PLRV, PVY, PVM, PVA, PVX and PVS. They can cause up 90% loss tubers in the field. Common methods currently used ELISA conventional real-time PCR, but both time-consuming, former needs high capacity...

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...
