In this study a new begomovirus infecting <em>Cnidoscolus urens</em> (Euphorbiaceae) from Brazil has been characterized. The complete DNA-A sequence was used for species demarcation, phylogenetic and recombination analyzes with other previously reported begomoviruses. The DNA-A (2585 nt) has a genome organization that is typical of the New World bipartite begomovirus, most closely related to tomato yellow spot virus, with <em>80.6% nucleotide identity. Based on the identity criterion for DNA-A established by the </em><em>Geminiviridae</em><em> Study Group of the </em><em>International Committee on Taxonomy of Viruses</em><em> of ≥ 91%, this isolate should be considered a member of a new species, for which the name “Cnidoscolus blistering yellow mosaic virus” (CnBYMV) is proposed. Phylogenetic analysis revealed that CnBYMV grouped with begomoviruses described in cultivated and non-cultivated plants from Brazil. </em>Results of recombination analysis indicated that the novel begomovirus was a recombinant, with cnidoscolus mosaic leaf deformation virus and sida mottle virus as <em>probable parents</em>.</p>}, journal={Comunicata Scientiae}, author={Costa de Oliveira, Maria Helloá and Ferro, Mayra and Monteiro Feijó, Frederico and Silvestre de Andrade Lima, Gaus and Pereira Assunção, Iraildes and Cavalcanti da Silva, Sarah Jacqueline}, year={2021}, month={Oct.}, pages={e3437} }
