Construction of Infectious Clones of Begomoviruses: Strategies, Techniques and Applications

Biology, 2021
Begomovirus has become a potential threat to the agriculture sector. It causes significant losses to several economically important crops. Given this considerable loss, the development of tools to study viral genomes and function is needed.

Statistical analysis on detecting recombination sites in DNA-beta satellites associated with the old world geminiviruses [PDF]

, 2010
Although an exchange of genetic information by recombination plays an important role in the evolution of viruses, it is not clear how it generates diversity.

Begomovirus Evolution and Disease Management

, 2006
Publisher Summary This chapter considers the knowledge of the roles of vector, viruses, and plant hosts in the emergence of begomovirus epidemics, and outlines areas in which further research is needed. It looks at the vector–virus–host interaction from an epidemiological and evolutionary perspective and considers how the understanding gained can be ...

A New Tomato-Infecting Begomovirus in Barbados

Plant 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.

Molecular and Biological Characterization of a New World Mono-/Bipartite Begomovirus/Deltasatellite Complex Infecting Corchorus siliquosus

Frontiers in Microbiology, 2020
The genus Begomovirus (family Geminiviridae) is the largest genus in the entire virosphere, with more than 400 species recognized. Begomoviruses are single-stranded DNA plant viruses transmitted by whiteflies of the Bemisia tabaci complex and are ...

From Metagenomics to Discovery of New Viral Species: Galium Leaf Distortion Virus, a Monopartite Begomovirus Endemic in Mexico

Frontiers in Microbiology, 2022
Begomoviruses (Family Geminiviridae) are a major group of emerging plant viruses worldwide. The knowledge of begomoviruses is mostly restricted to crop plant systems. Nevertheless, it has been described that non-cultivated plants are important reservoirs
