Popis: Tomato mild yellow leaf curl Aragua virus (ToMYLCV) is a begomovirus first reported infecting tomato (Solanum lycopersicum) and milkweed (Euphorbia heterophylla) in Venezuela. In this study, a ToMYLCV isolate (Zulia-219) was completely sequenced and its host range was evaluated. The DNA-A and DNA-B components of isolate Zulia-219 showed 93 and 85% nucleotide sequence identity with the respective counterparts of the ToMYLCV type strain. According to current demarcation criteria for begomovirus species, Zulia-219 is a new strain of ToMYLCV. Interestingly, tomato plants inoculated with ToMYLCV Zulia-219 displayed severe symptoms, including severe chlorotic leaf curling, in contrast to mild symptoms associated with the type strain of this begomovirus. These results indicate potential risks associated with this new ToMYLCV strain for tomato production in Venezuela.
