“…Non-cultivated species of the families Asteraceae, Caparaceae, Euphorbiaceae, Fabaceae, Labiatae, Malvaceae, Solanaceae and Sterculiaceae have been reported as hosts of many begomoviruses in Brazil and in several other countries in the Americas (Frischmuth et al, 1997;Roye et al, 1997;Faria and Maxwell, 1999;Fernandes et al, 1999;Idris et al, 2003;Jovel et al, 2004;Assunção et al, 2006;Amarakoon et al, 2008;Castillo-Urquiza et al, 2008;Barbosa et al, 2009;Silva et al, 2011;Silva et al, 2012;Tavares et al, 2012;Barreto et al, 2013). There is evidence that some of these begomoviruses from noncultivated hosts can be transmitted to cultivated species by the insect vector and by grafting (Arnaud et al, 2007;Castillo-Urquiza et al, 2007;Cotrim et al, 2007;Silva et al, 2010;Barreto et al, 2013;Rocha et al, 2013;Ramos-Sobrinho et al, 2014), highlighting the need to investigate these plants as reservoirs of viral diversity and as a source of new viruses which may cause diseases in crops.…”

Begomoviruses (whitefly-transmitted, single-stranded DNA plant viruses) are among the most damaging pathogens causing epidemics in economically important crops worldwide. Besides cultivated plants, many weed and wild hosts act as virus reservoirs where recombination may occur, resulting in new species. The aim of this study was to further characterise the diversity of begomoviruses infecting two major weed genera, Sida and Leonurus. Total DNA was extracted from samples collected in the states of Rio Grande do Sul, Paraná and Mato Grosso do Sul during the years 2009-2011. Viral genomes were enriched by rolling circle amplification (RCA), linearised into unit length genomes using various restriction enzymes, cloned and sequenced. A total of 78 clones were obtained: 37 clones from Sida spp. plants and 41 clones from Leonurus sibiricus plants. Sequence analysis indicated the presence of six bipartite begomovirus species and two alphasatellites. In Sida spp. plants we found Sida micrantha mosaic virus (SiMMV), Euphorbia yellow mosaic virus (EuYMV), and three isolates that represent new species, for which the following names are proposed: Sida chlorotic mottle virus (SiCMoV), Sida bright yellow mosaic virus (SiBYMV) and Sida golden yellow spot virus (SiGYSV), an Old World-like begomovirus. L. sibiricus plants had a lower diversity of begomoviruses compared to Sida spp., with only Tomato yellow spot virus (ToYSV) and EuYMV (for the first time detected infecting plants of the genus Leonurus) detected. Two satellite DNA molecules were found: Euphorbia yellow mosaic alphasatellite, for the first time detected infecting plants of the genus Sida, and a new alphasatellite associated with ToYSV in L. sibiricus. These results constitute further evidence of the high species diversity of begomoviruses in non-cultivated hosts, particularly Sida spp.

Molecular Characterization of a Novel Begomovirus Infecting Malva (Gaya guerkeana K. Schum.)

et al. 2018

The genus Begomovirus (family Geminirvidae) comprises circular single-stranded DNA viruses that infect both cultivated and non-cultivated hosts, being transmitted by the insect vector Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). This study aimed to conduct the molecular characterization of a novel begomovirus infecting the non-cultivated plant Gaya guerkeana K. Schum. (Malvaceae). A leaf sample of G. guerkeana was collected in the State of Pernambuco, Brazil, in 2010. Viral genomic components were amplified via RCA, cloned, and commercially sequenced. The full-length DNA-A sequence was used for phylogenetic analysis and pairwise comparisons with other previously reported begomoviruses. The begomovirus DNA-A from G. guerkeana was most closely related to the Sida mottle Alagoas virus (SiMoAV, JX871386), having 84.8% nucleotide identity. Using the ≥ 91% identity criteria for DNA-A established by the Geminivirus Study Group of the International Committee on Taxonomy of Viruses, this isolate was considered a putative new begomovirus species, and the name Gaya yellow mosaic virus (GaYMV) is suggested. The GaYMV isolate grouped with SiMoAV and other begomoviruses infecting Sida spp. from the State of Alagoas, Brazil. This is the first report of a begomovirus infecting G. guerkeana, indicating that this non-cultivated plant can act as a reservoir/source of begomoviruses.

“…In Brazil, EuYMV has been reported to cause mosaic disease in Euphorbia heterophylla since the 1950s [11] in addition to being found naturally infecting Macroptilium atropurpureum, Sida santaremensis, Crotalaria juncea and Solanum lycopersicum [4,12,13]. To date, EuYMV is the only begomovirus infecting euphorbiaceous hosts in Brazil that has been completely characterized [8].…”

Cnidoscolus mosaic leaf deformation virus: a novel begomovirus infecting euphorbiaceous plants in Brazil

et al. 2016

View full text Add to dashboard Cite

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.
