Résumé : A new genus-level geminivirus lineage isolated from the South African fynbos. The state of the art on the diversity of plant viruses mainly concerns those causing symptoms affecting plants of economic interest. However, wild plants have the potential to be reservoirs of viral biodiversity which contribute to the emergence of virus without necessarily showing symptoms. We have carried out over the past 10-months a preliminary study aiming at assessing the diversity of circular ssDNA viruses present at the interface between crops and wild plants in the South African fynbos. We have discovered a new geminivirus, which infects a wild spurge (Euphorbia caput-medusae). This virus is highly divergent from the current known members of the family Geminiviridae and is likely to represent a new previously unknown genus of this agriculturally highly relevant family of viruses. This virus, which is not obviously a recombinant of viruses in the known geminivirus genera, has features most similar to viruses in the genus Mastrevirus but it also has unique features among geminiviruses.
