Abstract

Most known mastreviruses (family Geminiviridae) infect members of the grass family, Poaceae. Although the greatest number of grass-infecting mastrevirus species have been discovered in Africa, it is apparent that the ten grass-infecting mastrevirus species that have so far only been discovered in south-east Queensland have a degree of diversity that rivals that observed in Africa. In this study, we have used a deep sequencing approach to identify two new mastrevirus species, tentatively named rice latent virus 1 and 2 (RLV 1 and 2), from two, undescribed wild rice species (Oryza AA genome group) in Cape York Peninsula, Queensland. The sequences of these new viruses had less than 70% identity with any previously identified mastrevirus, and therefore their discovery vastly expands the known diversity of monocot-infecting mastreviruses in Australia. This study also highlights the potential risks of novel crop pathogens emerging from uncultivated grass species, as the wild rice hosts are very closely related to domesticated rice.
