Stock indexing and Potato virus Y elimination from potato plants cultivated in vitro
Scientia Agricola, 2003 Potato cultivars (Solanum tuberosum L.) have shown degeneration or run out caused by viruses after several cycles of propagation using seed tubers from commercial fields.

Molecular Ecology, Volume 34, Issue 20, October 2025.ABSTRACT Plant viruses often alter host traits in ways that affect interactions with herbivores, potentially facilitating their own acquisition and transmission by insect vectors. However, little is known about the molecular mechanisms underlying this phenomenon.

The Plant Genome, Volume 18, Issue 3, September 2025.Abstract Potato wild relatives (Solanum section Petota) are a source of genetic diversity for climate‐smart improvement of modern cultivars (Solanum tuberosum). The allotetraploid Solanum acaule Bitter. has been previously used to introgress frost tolerance into potato cultivars such as Yukon Gold and Viking.

Plant Pathology, Volume 74, Issue 6, Page 1585-1592, August 2025.ToCV is not widely distributed in potato crops in São Paulo, but its transmission by Bemisia tabaci MEAM1 and MED and its high vertical transmission rate highlight the need for monitoring to mitigate its potential future impact. ABSTRACT Potato is a vital food source worldwide, but its production is frequently threatened by viral diseases.

Nucleolar localization of potato leafroll virus capsid proteins
Journal of General Virology, 2005 Potato leafroll virus (PLRV) encodes two capsid proteins, major protein (CP) and minor protein (P5), an extended version of the CP produced by occasional translational ‘readthrough’ of the CP gene. Immunogold electron microscopy showed that PLRV CP is located in the cytoplasm and also localized in the nucleus, preferentially ...

Molecular Plant Pathology, Volume 26, Issue 7, July 2025.GATA8 enhances the antiviral defence of tomato plants against tomato chlorosis virus by binding to the promoter of SnRK2, thereby regulating its expression. However, this process is counteracted by the viral p27 protein. ABSTRACT Tomato chlorosis virus (ToCV), a phloem‐restricted RNA virus within the genus Crinivirus of the family Closteroviridae ...

Mutational analysis of the proteinase function of Potato leafroll virus
Journal of General Virology, 2001 cDNA expression vectors of Potato leafroll virus (PLRV) were used to analyse specific mutations in the proteinase and replicase domains of the proteins encoded by ORF1 and ORF2. Agrobacterium-mediated DNA transfer was used to introduce a PLRV RNA expression unit, controlled by the 35S promoter of Cauliflower mosaic virus, into potato leaf cells ...

Journal of Applied Entomology, Volume 149, Issue 3, Page 442-451, April 2025.ABSTRACT Faba bean can be infected by Pea necrotic yellow dwarf virus (PNYDV), a novel pathogen throughout Europe, and transmitted persistently by several legume‐colonising aphid species. Recent field screenings in Austria and Germany of different faba bean varieties were encouraging as consistently the lowest viral symptom development in the variety ...
