Revision of Begomovirus taxonomy based on pairwise sequence comparisons [PDF]
Archives of Virology, 2015 Viruses of the genus Begomovirus (family Geminiviridae) are emergent pathogens of crops throughout the tropical and subtropical regions of the world. By virtue of having a small DNA genome that is easily cloned, and due to the recent innovations in cloning and low-cost sequencing, there has been a dramatic increase in the number of available ...

Cryo-EM Structure of a Begomovirus Geminate Particle [PDF]
International Journal of Molecular Sciences, 2019 Tobacco curly shoot virus, a monopartite begomovirus associated with betasatellite, causes serious leaf curl diseases on tomato and tobacco in China. Using single-particle cryo-electron microscopy, we determined the structure of tobacco curly shoot virus (TbCSV) particle at 3.57 Å resolution and confirmed the characteristic geminate architecture with ...

Multiple infections of Begomovirus on its host plants
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Begomovirus infection has been reported to cause many important diseases on vegetable crops in Indonesia. This research was conducted to reconfirm the identity of Begomovirus infecting several host plants. Plant samples were taken from several DI Yogyakarta locations, i.e., Sleman, Kulon Progo, and Bantul. Amplification of virus

Molecular Characterization and Pathogenicity of Watermelon Isolates of Begomovirus cucurbitachinaense [PDF]
International Journal of Molecular SciencesSquash leaf curl China virus (SLCCNV) belongs to the species Begomovirus cucurbitachinaense in the genus Begomovirus and can infect some Cucurbitaceae crops except for watermelon (Citrullus lanatus). In this study, watermelon plants showing symptoms typical to begomovirus infection in field were observed in Zhejiang Province of China, and SLCCNV ...

Phylogeographic analysis of Begomovirus coat and replication-associated proteins [PDF]
Journal of General VirologyBegomoviruses are globally distributed plant pathogens that significantly limit crop production. These viruses are traditionally described according to phylogeographic distribution and categorized into two groups: begomoviruses from the Africa, Asia, Europe and Oceania (AAEO) region and begomoviruses from the Americas.

Characterisation of a Betasatellite Associated With Tomato Yellow Leaf Curl Guangdong Virus and Discovery of an Unusual Modulation of Virus Infection Associated With C4 Protein [PDF]
Molecular Plant Pathology, Volume 26, Issue 1, January 2025.The C4 protein, encoded by tomato yellow leaf curl Guangdong virus (TYLCGdV), does not inhibit PTGS or TGS; the C4 protein modulates TYLCGdV infection by regulating the cytosine methylation level of viral genome at different infection stages. ABSTRACT Tomato yellow leaf curl Guangdong virus (TYLCGdV), a monopartite begomovirus first identified in 2004,

The diversification of begomovirus populations is predominantly driven by mutational dynamics [PDF]
Virus Evolution, 2017 Abstract Begomoviruses (single-stranded DNA plant viruses) are responsible for serious agricultural threats. Begomovirus populations exhibit a high degree of within-host genetic variation and evolve as quickly as RNA viruses. Although the recombination-prone nature of begomoviruses has been extensively demonstrated, the relative ...

Journal of General Virology, 2007 DNA β is a circular single-stranded satellite DNA which co-infects with certain monopartite helper begomoviruses to cause economically important diseases, such as cotton leaf curl disease (CLCuD). DNA β encodes a single protein, βC1. Tomato leaf curl New Delhi virus (ToLCNDV) is a bipartite begomovirus in which both DNA A and DNA B are required for ...

Gene Overlapping as a Modulator of Begomovirus Evolution [PDF]
Microorganisms, 2022 In RNA viruses, which have high mutation—and fast evolutionary— rates, gene overlapping (i.e., genomic regions that encode more than one protein) is a major factor controlling mutational load and therefore the virus evolvability. Although DNA viruses use host high-fidelity polymerases for their replication, and therefore should have lower mutation ...
