Brasília, DF: SBVc2018 aBegomoviruses are part of the Geminivirus family of single-stranded DNA viruses, with members of economic importance to crops such as tomato and beans. Begomovirus is a genus of one or two ssDNA components, with twined icosahedral particles, transmitted by the whitefly Bemisia tabaci. There are more than 14 begomoviruses described infecting tomatoes in Brazil. In common beans, the begomovirus Bean golden mosaic virus (BGMV) is responsible for losses that can reach up to 100% under field conditons. Although noncultivated plants are not important economically, they may serve as sources of inoculum when they harbor a virus of an economically important host. Besides this, the noncultivated plants are considerated as a source of high mutation and recombination rates. Two noncultivated and unrelated plant species were collected, Neonotonia wightii and Parthenium hysterophorus, displaying characteristic symptoms of infection by Geminivirus, in Santo Antonio de Goiás-GO, Brazil. aPlant viruses aWeeds aBegomoviroses1 aFARIA, J.
