Appearances can be deceptive: Revealing a hidden viral infection with deep sequencing in a plant quarantine context [PDF]

, 2009
Comprehensive inventories of plant viral diversity are essential for effective quarantine and sanitation efforts. The safety of regulated plant material exchanges presently relies heavily on techniques such as PCR or nucleic acid hybridisation, which ...

A Shift in Begomovirus coheni Populations Associated With Tomato Yellow Leaf Curl Disease Infecting Tomato Cultivars in the Southeastern United States

Plant Pathology, Volume 74, Issue 5, Page 1277-1289, June 2025.
A shift in Begomovirus coheni populations associated with tomato yellow leaf curl disease (TYLCD) in tomato cultivars might facilitate the emergence of tomato yellow leaf curl virus‐Georgia (TYLCV‐GA) in natural conditions. ABSTRACT Tomato yellow leaf curl virus (TYLCV) is a major pathogen causing tomato yellow leaf curl disease (TYLCD), significantly ...

Plant viruses convergently target NPR1 with various strategies to suppress salicylic acid‐mediated antiviral immunity

Journal of Integrative Plant Biology, Volume 67, Issue 5, Page 1395-1412, May 2025.
Viral infection triggers monomerization and nuclear translocation of the salicylic acid receptor NONEXPRESSOR OF PATHOGENESIS‐RELATED GENES1 (NPR1) to activate pathogenesis‐related gene expression. Nevertheless, viruses have developed one or more proteins to target NPR1 and impair its functionality through mechanisms such as inducing its degradation ...

The Transcriptome Response of African and South American Cassava (Manihot esculenta) to Infection by East African Cassava Mosaic Virus‐Uganda

Plant Pathology, Volume 74, Issue 4, Page 1068-1077, May 2025.
The early defence response in cassava plants is associated with EACMV‐Ug resistance, while the susceptible varieties' response is delayed and expresses fewer unique differentially expressed genes. ABSTRACT Cassava mosaic begomoviruses (CMBs) cause the economically important cassava mosaic disease (CMD) in cassava.

Geminivirus Rep Protein Interferes with the Plant DNA Methylation Machinery and Suppresses Transcriptional Gene Silencing [PDF]

, 2015
Viruses are masters at circumventing host defenses and manipulating the cellular environment for their own benefit. The replication of the largest known family of single-stranded DNA viruses, Geminiviridae, is impaired by DNA methylation but the fact ...

A novel geminivirus‐derived 3′ flanking sequence of terminator mediates the gene expression enhancement

Plant Biotechnology Journal, Volume 23, Issue 4, Page 1053-1066, April 2025.
Summary Exploring the new elements to re‐design the expression cassette is crucial in synthetic biology. Viruses are one of the most important sources for exploring gene expression elements. In this study, we found that the DNA sequence of the SBG51 deltasatellite from the Sweet potato leaf curl virus (SPLCV) greatly enhanced the gene expression when ...

A Novel Strain of Tomato Leaf Curl New Delhi Virus Has Spread to the Mediterranean Basin

Viruses, 2016
Tomato leaf curl New Delhi virus (ToLCNDV) is a whitefly-transmitted bipartite begomovirus (genus Begomovirus, family Geminiviridae) that causes damage to multiple cultivated plant species mainly belonging to the Solanaceae and Cucurbitaceae families ...

Mise au point de deux tests PCR multiplexes pour détecter simultanément des formes recombinantes et non-recombinantes du Tomato yellow leaf curl virus au Maroc [PDF]

, 2013
Le Tomato yellow leaf curl virus (TYLCV, genre Begomvirus, famille Geminiviridae) a été isolé pour la première fois au Maroc en 1998 (Peterschmitt et al., 1999) et le Tomato yellow leaf curl Sardinia virus (TYLCSV) en 1999 (Monci et al., 2000).
