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...

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, ...
