Begomoviruses have been detected infecting the weed Cnidoscolus urens (family Euphorbiaceae) since 2004, but the viral species to which these viruses belonged was not known. Here, we report for the first time the complete genome sequence of a bipartite begomovirus obtained from C. urens collected in the state of Alagoas, Brazil. This isolate met the criteria to be classified as a member of a new begomovirus species, and the tentative name cnidoscolus mosaic leaf deformation virus (CnMLDV) is proposed. Pairwise sequence comparisons and phylogenetic analysis showed that the DNA-A genomic component of CnMLDV is most closely related to that of passionfruit severe leaf distortion virus, with 86.3 % nucleotide sequence identity.
