Differentiation of PVY isolates depending on criterion of evaluation

Acta Agrobotanica, 2013
In 2000-2001 35 isolates of Potato virus Y(PVY) were characterized by serological and biological methods. These isolates represented 5 distinct strains: PVY<sup>C<sup>, PVY<sup>O<sup>, PVY<sup>N<sup>, PVY<sup>N<sup> W, PVY<sup>NTN<sup>.

Cucumber mosaic virus Infection Transiently Breaks dsRNA-Induced Transgenic Immunity to Potato virus Y in Tobacco

Molecular Plant-Microbe Interactions, 2003
Post-transcriptional gene silencing (PTGS), an intrinsic plant defense mechanism, can be efficiently triggered by double stranded (ds)RNA-producing transgenes and can provide high level virus resistance by specific targeting of cognate viral RNA.

Comparison of Bacterial Expression Systems Based on Potato Virus Y-like Particles for Vaccine Generation

Vaccines, 2022
Plant-based virus-like particle (VLP) vaccines have been studied for years, demonstrating their potential as antigen-presenting platforms. In this paper, we describe the development of, and compare between, simple Escherichia coli-based antigen display ...

Unfolding Plant Defence: Endoplasmic Reticulum Stress Signalling at the Plant‐Pathogen Interface

Plant Biotechnology Journal, Volume 24, Issue 8, Page 4799-4822, August 2026.
ABSTRACT The endoplasmic reticulum (ER) stress response, a conserved proteostasis network, has emerged as a central hub that reprograms plant immunity during pathogen attack. This review synthesises how plants harness ER‐stress signalling to mount multilayered defences and how pathogens have evolved counterstrategies to subvert these pathways.

Systemic infection of tobacco mosaic virus is limited by upward transport and phloem unloading without coat protein

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Coat protein (CP) is widely viewed as essential for systemic infection of tobacco mosaic virus (TMV), yet the mechanistic basis of this requirement remains incompletely resolved. In this study, we show that TMV can still achieve long‐distance vascular transport in the absence of CP, but systemic infection becomes intermittent because the ...

Modulation of Expression of PVY^NTN RNA-Dependent RNA Polymerase (NIb) and Heat Shock Cognate Host Protein HSC70 in Susceptible and Hypersensitive Potato Cultivars

Vaccines, 2021
Potato virus Y (PVY) belongs to the genus Potyvirus and is considered to be one of the most harmful and important plant pathogens. Its RNA-dependent RNA polymerase (RdRp) is known as nuclear inclusion protein b (NIb).

De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 2073-2086, July 2026.
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.

Hazai PVY izolátumok levéltetű átvitelében szerepet játszó gének molekuláris jellemzése = Molecular characterisation of genes playing role in aphid transmission of Hungarian PVY isolates [PDF]

, 2009
A potyvírusok levéltetű átviteléért a segítő fehérje (HC-Pro) és a köpenyfehérje (CP) három szakasza felelős: a HC-Pro amino-terminális végén található KITC motívum, a karboxi-terminális végén lévő PTK aminosav triplet és a CP DAG motívum.

Development of an attenuated potato virus Y mutant carrying multiple mutations in helper-component protease for cross-protection

Virus Research
Tobacco (Nicotiana tabacum) is one of the major cash crops in China. Potato virus Y (PVY), a representative member of the genus Potyvirus, greatly reduces the quality and yield of tobacco leaves by inducing veinal necrosis.
