Molecular characterization of previously elusive badnaviruses associated with symptomatic cacao in the New World
Suspected virus-like symptoms were observed in cacao plants in Trinidad during 1943, and the viruses associated with these symptoms were designated as strains A and B of cacao Trinidad virus (CTV). However, vi...

Article
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, ...

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...

Article
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...

Phylogenetic relationships, recombination analysis, and genetic variability among diverse variants of tomato yellow leaf curl virus in Iran and the Arabian Peninsula: further support for a TYLCV center of diversity
The discovery of five strains of TYLCV in Iran, including the most well-known and widespread, TYLCV-IL, spurred a detailed study of the full-length genomes of additional TYLCV field isolates and an in-depth a...
