Fungal, not insect: Revisiting a misidentified Bemisia tabaci protein interacting with a begomovirus coat protein. [PDF]

Insect Mol Biol
A small heat‐shock protein (HSP16) previously reported as insect‐derived in Bemisia tabaci actually originates from a fungal species of the genus Wallemia. BLAST, genome survey and phylogenetic analyses support the fungal origin and clarify persistent misattribution in the literature.

Cucurbit Leaf Crumple Virus: An Important Pathogen of Cucurbit and Snap Bean Crops. [PDF]

Mol Plant Pathol
Cucurbit leaf crumple virus (CuLCrV) is an emerging pathogen in the New World. High whitefly abundance and transmission efficiency, mixed infections, weed reservoirs and limited host resistance challenge cucurbit and snap bean production. ABSTRACT Taxonomy Cucurbit leaf crumple virus (CuLCrV); Begomovirus cucurbitae; Geminiviridae; Geplafuvirales ...

Gene Overlapping as a Modulator of Begomovirus Evolution [PDF]

Microorganisms, 2022
In RNA viruses, which have high mutation—and fast evolutionary— rates, gene overlapping (i.e., genomic regions that encode more than one protein) is a major factor controlling mutational load and therefore the virus evolvability. Although DNA viruses use host high-fidelity polymerases for their replication, and therefore should have lower mutation ...

Insights Into Virus-Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops. [PDF]

Physiol Plant
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.

Viral and Host Factors Involved in Host Gain and Host Loss by Tomato Leaf Curl Begomoviruses in Tomato and Cucumbers. [PDF]

Mol Plant Pathol
Begomoviruses have jumped hosts between tomatoes and cucumbers, and we found that a short region (transcriptional activator and replication enhancer proteins, TrAp and REn) of tomato leaf curl New Delhi virus is mainly responsible for host jump. ABSTRACT Begomoviruses transmitted by whiteflies cause severe crop losses worldwide.

SLCMV-Encoded BC1 Protein Suppresses Photosynthesis by Disrupting Chloroplast Structure and Gene Expression. [PDF]

Mol Plant Pathol
SLCMV infection suppresses photosynthesis by down‐regulating chloroplast‐ and photosystem‐related genes and disrupting chloroplast structure, a process largely mediated by the viral protein BC1. ABSTRACT Sri Lankan cassava mosaic virus (SLCMV) is a highly destructive plant virus that poses a significant threat to cassava cultivation.

Begomovirus Caboniensis: a New Bipartite Begomovirus Isolated From Cnidoscolus Urens in Brazil

, 2021
Abstract A novel bipartite begomovirus infecting Cnidoscolus urens (Euphorbiaceae) from Pernambuco State, Brazil has been characterized. The complete DNA-A (2657 to 2692 nt) and DNA-B (2622 nt) components of the viral isolates showed a typical genome organization of New World bipartite begomoviruses.

Current Status and Complexity of Three Begomovirus Species in Pepper Plants in Lowlands and Highlands in Java Island, Indonesia

Viruses, 2023
Three primary species from the Begomovirus genus, Pepper yellow leaf curl Indonesia virus (PepYLCIV), Tomato yellow leaf curl Kanchanaburi virus (TYLCKaV), and Tomato leaf curl New Delhi virus (ToLCNDV), are suspected of spreading throughout pepper ...
