A New Tomato-Infecting Begomovirus in Barbados

open access: yesPlant Disease, 2000
In September 1998, tomato plants in Barbados exhibited symptoms of severe leaf curling without marginal chlorosis. These symptoms were often associated with an increase in whitefly (Bemisia tabaci) populations. DNA was extracted from leaf tissue from symptomatic tomato plants.

Red-light is an environmental effector for mutualism between begomovirus and its vector whitefly

open access: yesbioRxiv, 2020
Environments such as light condition influence the spread of infectious diseases by affecting insect vector behavior. However, whether and how light affects the host defense which further affect insect preference and performance, remains unclear, nor has

A Begomovirus Nuclear Shuttle Protein-Interacting Immune Hub: Hijacking Host Transport Activities and Suppressing Incompatible Functions

open access: yesFrontiers in Plant Science, 2020
Begomoviruses (Geminiviridae family) represent a severe constraint to agriculture worldwide. As ssDNA viruses that replicate in the nuclei of infected cells, the nascent viral DNA has to move to the cytoplasm and then to the adjacent cell to cause ...

Global Scenario of Begomovirus Diseases in Vegetable Crops

open access: yesVegetable Science
Whitefly-transmitted begomoviruses are the major threats to the cultivation of vegetable crops worldwide. Begomoviruses infecting vegetables have a broad host range and are distributed among all continents in which vegetables are grown in open fields and

Ty-6, a major begomovirus resistance gene on chromosome 10, is effective against Tomato yellow leaf curl virus and Tomato mottle virus

open access: yesTheoretical and Applied Genetics, 2019
Ty-6 is a major resistance gene on chromosome 10 of tomato that provides resistance against monopartite and bipartite begomoviruses and complements resistance conferred by the known Ty-3 and ty-5 genes.

Characterization of Curtovirus V2 Protein, a Functional Homolog of Begomovirus V2

open access: yesFrontiers in Plant Science, 2020
Geminiviruses are single-stranded DNA plant viruses with circular genomes packaged within geminate particles. Among the Geminiviridae family, Begomovirus and Curtovirus comprise the two best characterized genera.

Apoptosis in a Whitefly Vector Activated by a Begomovirus Enhances Viral Transmission

open access: goldmSystems, 2020
Of the approximately 1,100 known plant viruses, about one-third are DNA viruses that are vectored by insects. Plant virus infections often induce cellular and molecular responses in their insect vectors, which can, in many cases, affect the spread of ...

South West Indian Ocean islands tomato begomovirus populations represent a new major monopartite begomovirus group

open access: yesJournal of General Virology, 2005
Biological and molecular properties of Tomato leaf curl Madagascar virus isolates from Morondova and Toliary (ToLCMGV-[Tol], -[Mor]), Tomato leaf curl Mayotte virus isolates from Dembeni and Kahani (ToLCYTV-[Dem], -[Kah]) and a Tomato yellow leaf curl virus isolate from Réunion (TYLCV-Mld[RE]) were determined.

Multiplexed editing of a begomovirus genome restricts escape mutant formation and disease development

open access: yesPLoS ONE, 2019
Whitefly-transmitted begomoviruses cause serious damage to many economically important food, feed, and fiber crops. Numerous vegetable crops are severely affected and chilli leaf curl virus (ChiLCV) is the most dominant and widely distributed begomovirus

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 ...
