Advances in Understanding Begomovirus Satellites
Annual Review of Phytopathology, 2013Begomoviruses are numerous and geographically widespread viruses that cause devastating diseases in many crops. Monopartite begomoviruses are frequently associated with betasatellites or alphasatellites. Both betasatellite and alphasatellite DNA genomes are approximately half the size of begomovirus DNA genomes.

Begomovirus: Exploiting the Host Machinery for Their Survival
Journal of Modern Agriculture and Biotechnology, 2023Begomoviruses are the most prevalent plant-infecting virus genus, identified by a circular single-stranded DNA genome. The proteins encoded by these viruses are multifunctional and effectively modulate the host's cellular response during infection. Begomovirus-host interactions alter host gene expression patterns, redirect signaling pathways, disturb ...

The genus Begomovirus belonging to the family Geminiviridae constitutes the largest group of plant-infecting DNA viruses affecting a wide range of dicotyledonous plants. The genus is one of the nine genera of the family Geminiviridae which have characteristic geminate (paired) particles (20 × 38 nm) consisting of two incomplete icosahedra (T = 1 ...

The whitefly-transmitted begomoviruses (family: Geminiviridae) emerged, during the late twentieth century, as serious pathogens of many vegetable crops across tropical and subtropical regions of the world. This importance is due to the economic impact of the diseases they cause (Morales and Anderson 2001).

Complementation of bipartite begomovirus movement functions by topocuviruses and curtoviruses
Archives of Virology, 2001The DNA A components of bipartite species of the genus Begomovirus (family Geminiviridae) encode all viral functions required for replication and encapsidation but require gene products encoded on DNA B for cell-to-cell movement in plants. We demonstrate that geminiviruses of the genera Curtovirus and Topocuvirus are able to trans-complement efficient ...

Begomovirus infection in tomato fruit
2017In an era of globalization and increased food trade, and considering the implementations of climate change on establishment of pathogens into new areas, it is of importance to monitor traded plant material for the presence of plant pathogens. Tomato is economically one of the most important vegetable crop worldwide and it is susceptible to more than ...

Letter to the Editor: Mastrevirus sequences in a begomovirus-infected plant
Virus Genes, 2012Recombination is a major driver of diversification of geminiviruses and is believed to be, for a large part, responsible for the present taxonomic structure of the family Geminiviridae. Examples of recent intergeneric recombination between viruses of the genera Begomovirus and Mastrevirus remain to be identified.
