Diversity, recombination and misclassification in the family Geminiviridae: Insight from bioinformatics analysis. [PDF]

PLoS ONE
The family Geminiviridae comprises 15 genera and over 500 species of diverse plant-infecting viruses. Previous studies on this virus's diversity primarily focused on the members' selection without considering the entire genomic divergence.

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 ...

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.

Replication mechanisms of circular ssDNA plant viruses and their potential implication in viral gene expression regulation [PDF]

mBio, 2023
The replication of members of the two circular single-stranded DNA (ssDNA) virus families Geminiviridae and Nanoviridae, the only ssDNA viruses infecting plants, is believed to be processed by rolling-circle replication (RCR) and recombination-dependent ...

Maize Streak Virus: Single and Gemini Capsid Architecture [PDF]

Viruses
Geminiviridae are ssDNA plant viruses whose control has both economical and agricultural importance. Their capsids assemble into two distinct architectural forms: (i) a T = 1 icosahedral and (ii) a unique twinned quasi-isometric capsid.

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.

Molecular characterization of Euphorbia caput-medusae stunt virus: Evidence for the existence of a new genus within the family Geminiviridae [PDF]

, 2013
Studies focusing on phytoviruses isolated from the wild are rare. Nevertheless, even if those studies remain scarce, it is increasingly accepted that viruses coming from wild plants might play a role on disease emergence and in the functioning of ...

To be or not to be a virus: A novel chimeric circular Rep-encoding single stranded DNA virus with interfamilial gene exchange illustrates the considerable evolutionary capacity of ssDNA viruses. [PDF]

PLoS ONE
Viruses in the family Geminiviridae cause significant economic losses in numerous crops worldwide. Some geminiviruses are often associated with satellite DNA molecules, such as alphasatellites (familly Alphasatellitidae), that require the assistance of a

Integrative multi-omics approach identified emerging viral threat in Theobroma cacao plants [PDF]

BMC Plant Biology
Background Theobroma cacao seeds are the source of chocolate and other valuable products. Pathogens can damage cocoa beans, reducing yield and quality. This study examined viruses linked to chlorosis and leaf deformation in cocoa plants in Bahia, Brazil,
