ICTV Virus Taxonomy Profile: Geminiviridae [PDF]

Journal of General Virology, 2017
The geminiviruses are a family of small, non-enveloped viruses with single-stranded, circular DNA genomes of 2500–5200 bases. Geminiviruses are transmitted by various types of insect (whiteflies, leafhoppers, treehoppers and aphids). Members of the genus Begomovirus are transmitted by whiteflies, those in the genera Becurtovirus, Curtovirus ...

Fangorn Forest (F2): a machine learning approach to classify genes and genera in the family Geminiviridae [PDF]

BMC Bioinformatics, 2017
Background Geminiviruses infect a broad range of cultivated and non-cultivated plants, causing significant economic losses worldwide. The studies of the diversity of species, taxonomy, mechanisms of evolution, geographic distribution, and mechanisms of ...

Geminiviridae and Alphasatellitidae Diversity Revealed by Metagenomic Analysis of Susceptible and Tolerant Tomato Cultivars across Distinct Brazilian Biomes

Viruses
The diversity of Geminiviridae and Alphasatellitidae species in tomatoes was assessed via high-throughput sequencing of 154 symptomatic foliar samples collected from 2002 to 2017 across seven Brazilian biomes.

Characterization of non-coding DNA satellites associated with sweepoviruses (genus Begomovirus, Geminiviridae) - definition of a distinct class of begomovirus-associated satellites [PDF]

Frontiers in Microbiology, 2016
Begomoviruses (family Geminiviridae) are whitefly-transmitted, plant-infecting single-stranded DNA viruses that cause crop losses throughout the warmer parts of the World.

Two dicot-infecting mastreviruses (family Geminiviridae) occur in Pakistan

Archives of Virology, 2008
Most mastreviruses (family Geminiviridae) infect monocotyledonous hosts and are transmitted by leafhopper vectors. Only two mastrevirus species, Tobacco yellow dwarf virus from Australia and Bean yellow dwarf virus (BeYDV) from South Africa, have been identified whose members infect dicotyledonous plants.

Identification of a single-stranded DNA virus associated with citrus chlorotic dwarf disease, a new member in the family Geminiviridae [PDF]

Virology, 2012
In the attempt to identify the causal agent of Citrus chlorotic dwarf disease (CCDD), a virus-like disorder of citrus, the small RNA fraction and total DNA from symptomatic citrus plants were subjected to high-throughput sequencing. DNA fragments deriving from an apparently new geminivirus-like agent were found and assembled by NGS to re-construct the ...

A genome-wide pairwise-identity-based proposal for the classification of viruses in the genus Mastrevirus (family Geminiviridae) [PDF]

Archives of Virology, 2013
Recent advances in the ease with which the genomes of small circular single-stranded DNA viruses can be amplified, cloned, and sequenced have greatly accelerated the rate at which full genome sequences of mastreviruses (family Geminiviridae, genus Mastrevirus) are being deposited in public sequence databases.

Involvement of C4 protein of beet severe curly top virus (family Geminiviridae) in virus movement. [PDF]

PLoS ONE, 2010
BACKGROUND: Beet severe curly top virus (BSCTV) is a leafhopper transmitted geminivirus with a monopartite genome. C4 proteins encoded by geminivirus play an important role in virus/plant interaction.

A novel species of mastrevirus (family Geminiviridae) isolated from Digitaria didactyla grass from Australia

Archives of Virology, 2010
Mastreviruses (family Geminiviridae) that infect monocotyledonous plants occur throughout the temperate and tropical regions of Asia, Africa, Europe and Australia. Despite the identification of a very diverse array of mastrevirus species whose members infect African monocots, few such species have been discovered in other parts of the world.

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.
