Accumulation of 24 nucleotide transgene‐derived siRNAs is associated with crinivirus immunity in transgenic plants [PDF]

Molecular Plant Pathology, 2018
Summary RNA silencing is a conserved antiviral defence mechanism that has been used to develop robust resistance against plant virus infections. Previous efforts have been made to develop RNA silencing‐mediated resistance to criniviruses, yet none have given immunity.

The Heterologous Expression of the p22 RNA Silencing Suppressor of the Crinivirus Tomato Chlorosis Virus from Tobacco Rattle Virus and Potato Virus X Enhances Disease Severity but Does Not Complement Suppressor-Defective Mutant Viruses [PDF]

Viruses, 2017
To counteract host antiviral RNA silencing, plant viruses express suppressor proteins that function as pathogenicity enhancers. The genome of the Tomato chlorosis virus (ToCV) (genus Crinivirus, family Closteroviridae) encodes an RNA silencing suppressor,

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 ...

Phylogenetic Analysis of Cucurbit Chlorotic Yellows Virus from Melon in 2020 in Chungbuk, Korea [PDF]

Research in Plant Disease, 2023
Cucurbit chlorotic yellows virus (CCYV) is a plant virus that causes damage to cucurbit crops such as watermelon and cucumber, and is transmitted by an insect vector known as the whitefly. Since CCYV was first detected on cucumber in Chungbuk in 2018, it

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 ...

High throughput sequencing for the detection and characterization of new virus found in arracacha (Arracacia xanthorrhiza)

Scientia Agropecuaria, 2021
Arracacha is a root crop cultivated in several countries of South America. The commercial product, which is the storage root, has multiple nutritional properties: its fine starch makes it easily digestible, and it contains high levels of calcium and ...

Neophytadiene, a Plant Specialized Metabolite, Mediates the Virus-Vector-Plant Tripartite Interactions. [PDF]

Adv Sci (Weinh)
Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

Mixed Infections of Plant Viruses in Crops: Solo vs. Group Game

Proceedings, 2020
Plant diseases are responsible for considerable economic losses in agriculture worldwide. Recent surveys and metagenomics approaches reveal a higher than expected incidence of complex diseases, like those caused by mixed viral infections.
