Cryptic species‐specific transmission of the invasive begomovirus tomato leaf curl New Delhi virus by the whitefly Bemisia tabaci

open access: yesNew Plant Protection, EarlyView.
ToLCNDV is typically transmitted by the whitefly Bemisia tabaci, but the efficiency of transmission varies among different cryptic species. The retention and circulation of viruses in insect vectors are crucial determinants of successful transmission to new plants.

Metagenomics of Neotropical Single-Stranded DNA Viruses in Tomato Cultivars with and without the Ty-1 Gene

open access: yesViruses, 2020
A complex of begomoviruses (Geminiviridae) can cause severe tomato yield losses in the neotropics. Here, next-generation sequencing was employed for large-scale assessment of single-stranded (ss)DNA virus diversity in tomatoes either harboring or lacking

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

open access: yesAnnals of Applied Biology, EarlyView.
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.

Incidence and Molecular Identification of Begomoviruses Infecting Tomato and Pepper in Myanmar

open access: yesPlants, 2022
In Myanmar, yellow mosaic and leaf curl diseases caused by whitefly-transmitted begomoviruses are serious problems for vegetables such as tomatoes and peppers. To investigate the incidence of begomoviruses in Myanmar between 2017 and 2019, a field survey

Molecular evidence for the association of a strain of Uganda variant of East African cassava mosaic virus to symptom severity in cassava (Manihot esculenta Crantz) fields in Togo [PDF]

open access: yes, 2009
: Problem statement: This study was carried out to demonstrate that the severity of Cassava Mosaic Disease (CMD) in Togo, is not only influenced by synergism between cassava Begomoviruses in presence, but essentially by recombination between the ...

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

open access: yesAnnals of Applied Biology, EarlyView.
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.

Impact of some crop management practices on tomato infestation/infection by the whitefly-begomovirus complex in Cuba [PDF]

open access: yes, 2013
Introduction. In the framework of the INCO-BETOCARIB Project titled "Begomovirus disease management for sustainable production of tomato in the Caribbean" which operated from 2003- 2006, we conducted a survey aiming at assessing the impact of cultural ...

Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection

open access: yesNew Phytologist, EarlyView.
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

Identification of Begomoviruses from Three Cryptic Species of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) in Nepal

open access: yesAgronomy, 2021
The Bemisia tabaci species complex consists of at least 44 cryptic species, which are potential vectors of approximately 320 begomovirus species, most of which are significant plant viruses.

Begomovirus quasispecies adapt to hosts by exploring different sequence space without changing their consensus sequences [PDF]

open access: yes, 2014
Geminiviruses possess single-stranded circular DNA genomes that depend on cellular polymerases for replication in the host nucleus. In plant hosts, geminivirus populations behave as ensembles of mutant and recombinant genomes.
