Weather Conditions and the Risk of Tomato Spotted Wilt Virus (TSWV) in Tomato Producing Areas in Southern Ghana

Plant-Environment Interactions, Volume 7, Issue 1, February 2026.
ABSTRACT Tomato farmers in southern Ghana incur losses due to the infection of crops by the tomato spotted wilt virus (Orthotospovirus tomatomaculae). The occurrence of the virus varies among individual tomato crops, influenced by the vector population and changing weather patterns. This study investigates the effect of early spring weather conditions (

Genetic recombination among tomato yellow leaf curl virus isolates in commercial tomato crops in Kuwait drives emergence of virus diversity: a comparative genomic analysis

BMC Research Notes, 2023
Objective Whitefly-transmitted tomato yellow leaf curl virus (TYLCV) continues to be a major constraint to tomato production in Kuwait. However, very limited information is available about the population structure and genetic diversity of TYLCV infecting

Suppression of RNA Silencing by TYLCV During Viral Infection [PDF]

, 2009
The Israeli isolate of Tomato yellow leaf curl geminivirus (TYLCV-Is) is a major tomato pathogen, causing extensive (up to 100%) crop losses in Israel and in the south-eastern U.S. (e.g., Georgia, Florida). Surprisingly, however, little is known about the molecular mechanisms of TYLCV-Is interactions with tomato cells.

The Molecular Cochaperone NbSGT1 May Function as an Endogenous Suppressor of RNA Silencing That Is Recruited by a Potyvirus in Infection of Plants

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.
The molecular co‐chaperone NbSGT1 interacts with potyviral HC‐Pro and promotes viral infection in plants. Notably, (1) NbSGT1 enhances the RSS activity of HC‐Pro and (2) NbSGT1 acts as an endogenous suppressor of RNA silencing (ESR), suppressing RNA silencing in plants.

An Analysis of TYLCV Damages under Regional Climate Changes

Journal of Korean Society of Rural Planning, 2015
The purpose of the research is to analyze damages of TYLCV (Tomato Yellow Leaf Curl Virus) in the context of climate changes and to find the spatial distribution of the damages and characteristics of regions. A TYLCV is generally known for a plant disease related to temperature. Its occurrence rate increases when temperature rises.

Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

Advanced Science, Volume 13, Issue 3, 14 January 2026.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...

Do stylet‐borne aphid‐transmitted viruses share the same binding sites?

Annals of Applied Biology, Volume 188, Issue 1, Page 87-101, January 2026.
Here, we tested if different stylet‐borne aphid‐transmitted viruses can compete for the same binding sites within the aphid stylets. We conducted sequential transmission assays of a potyvirus (ZYMV) followed by a cucumovirus (CMV) using Aphis gossypii as a vector and melon and pepper as test plants.

Identification and characterization of a cucumber accession resistant to tomato leaf curl New Delhi virus

Annals of Applied Biology, Volume 188, Issue 1, Page 182-194, January 2026.
Tomato leaf curl New Delhi virus (ToLCNDV) causes significant yield and fruit quality losses in cucurbit crops, particularly in the Mediterranean region. We identified a new source of resistance to ToLCNDV in cucumber (accession ABS.PE.045) and mapped resistance to four genomic intervals in chromosomes 1, 2, 6, and 7.

The Roles of Plant MicroRNAs in Defence Against Pathogens

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
miRNAs modulate plant immunity against various pathogens, including fungi, bacteria, viruses, nematodes and oomycetes, by targeting pathogen effectors and modulating hormonal signalling. ABSTRACT MicroRNAs (miRNAs) are a class of noncoding RNAs that play important roles in regulating gene expression.
