Identification of genetic sources with attenuated Tomato chlorosis virus-induced symptoms in Solanum (section Lycopersicon) germplasm
The whitefly-transmitted Tomato chlorosis virus (ToCV) (genus Crinivirus) is associated with yield and quality losses in field and greenhouse-grown tomatoes (Solanum lycopersicum) in South America. Therefore, the...

Capulavirus and Grablovirus: two new genera in the family Geminiviridae
Geminiviruses are plant-infecting single-stranded DNA viruses that occur in most parts of the world. Currently, there are seven genera within the family Geminiviridae (Becurtovirus, Begomovirus, Curtovirus, Eragr...

Open AccessTomato yellow leaf curl virus: No evidence for replication in the insect vector Bemisia tabaci
Begomovirus ssDNA plant virus (family Geminiviridae) replication within the Bemisia tabaci vector is controversial. Transovarial transmission, alteration to whitefly biology, or detection of viral transcripts in ...

Genetic diversity and silencing suppression activity of the p22 protein of Tomato chlorosis virus isolates from tomato and sweet pepper
As for other bipartite criniviruses (genus Crinivirus, family Closteroviridae), the genome of Tomato chlorosis virus encodes an RNA silencing suppressor, the protein p22, in the 3′-proxim...

Revision of Begomovirus taxonomy based on pairwise sequence comparisons
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, ...

Open AccessA sensitive method for the quantification of virion-sense and complementary-sense DNA strands of circular single-stranded DNA viruses
Circular single-stranded DNA (ssDNA) viruses are the smallest viruses known to infect eukaryotes. High recombination and mutation rates have conferred these viruses with an evolutionary potential that has faci...

Establishment of three new genera in the family Geminiviridae: Becurtovirus, Eragrovirus and Turncurtovirus
The family Geminiviridae includes plant-infecting circular single-stranded DNA viruses that have geminate particle morphology. Members of this family infect both monocotyledonous and dicotyledonous plants and ha...

Revisiting the classification of curtoviruses based on genome-wide pairwise identity
Members of the genus Curtovirus (family Geminiviridae) are important pathogens of many wild and cultivated plant species. Until recently, relatively few full curtovirus genomes have been characterised. However, w...
