A viral protein activates the MAPK pathway to promote viral infection by downregulating callose deposition in plants [PDF]

Nature Communications
Mitogen-activated protein kinase (MAPK) cascades are evolutionarily conserved in both plants and animals and play critical roles in activating innate immunity to defend against various pathogens.

Tomato antiviral ubiquitin-proteasome system recognizes viral 59 kDa protein to confer tomato chlorosis virus resistance [PDF]

Nature Communications
Viral diseases critically impact crop yields, necessitating insights into plant-pathogen recognition and resistance. In tomato (Solanum lycopersicum), tomato chlorosis virus (ToCV) employs 59 kDa protein (p59) to facilitate movement and degrade the host ...

Infectious Clones of Tomato Chlorosis Virus: Toward Increasing Efficiency by Introducing the Hepatitis Delta Virus Ribozyme [PDF]

Frontiers in Microbiology, 2021
Tomato chlorosis virus (ToCV) is an emergent plant pathogen that causes a yellow leaf disorder in tomato and other solanaceous crops. ToCV is a positive-sense, single stranded (ss)RNA bipartite virus with long and flexuous virions belonging to the genus ...

Differences in gene expression in whitefly associated with CYSDV-infected and virus-free melon, and comparison with expression in whiteflies fed on ToCV- and TYLCV-infected tomato [PDF]

BMC Genomics, 2019
Background Cucurbit yellow stunting disorder virus (CYSDV; genus Crinivirus, Closteroviridae) is transmitted in a semipersistent manner by the whitefly, Bemisia tabaci, and is efficiently transmitted by the widely prevalent B.

Tomato Chlorotic Virus Minor Coat Protein Interferes With the Host Proteasome Function by Competitive Disruption of SlPAD1-SlPA4 Interaction to Enhance Viral Infection. [PDF]

Mol Plant Pathol
CPm interacts with tomato SlPAD1 to block 26S proteasome function. Under physiological conditions, tomato SlPAD1 binds SlPA4 to form the 26S proteasome, maintaining protein homeostasis. During ToCV infection, viral CPm competitively interacts with SlPAD1, impairing proteasome function and inhibiting degradation of ubiquitinated proteins, thereby ...

GATA8-Mediated Antiviral Defence Is Countered by Tomato Chlorosis Virus-Encoded Pathogenicity Protein p27. [PDF]

Mol Plant Pathol
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 ...

First report of tomato chlorosis virus (ToCV) and detection of other viruses in field-grown tomatoes in North-Western region of India. [PDF]

Virusdisease, 2023
Tomato crop is known to be infected by large number of viruses across the globe causing severe losses in its yield. Accurate information on the distribution and incidence of different viruses is essential to implement virus control strategies. This study provides information on prevalence and distribution of different viruses infecting tomato crop in ...
