RESUMEN

A novel bipartite begomovirus infecting Cnidoscolus urens (Euphorbiaceae) from Pernambuco State, Brazil, has been characterized. The complete DNA-A (2657 nt) and DNA-B (2622 nt) components of the viral isolates show the typical genome organization of New World bipartite begomoviruses. DNA-A of the isolates had the highest percentage of nucleotide sequence identity (88.6-88.9%) to cnidoscolus mosaic leaf deformation virus. Based on the current classification criteria for the genus Begomovirus, the virus infecting C. urens should be considered a new member of the genus, and the name "cnidoscolus mild mosaic virus" is proposed for the virus, and the name "Begomovirus caboniensis" is proposed for its species.
