Abstract : Advances in molecular techniques used in viral metagenomics coupled with high throughput sequencing is rapidly expanding our knowledge of plant-associated virus diversity. Applying such approaches, we have identified five novel circular replication-associated protein (Rep)-encoding single-stranded (CRESS) DNA viruses from Poaceae and Apiaceae plant from South Africa and New Zealand. These viruses have a simple genomic organization, including two open reading frames that likely encode a Rep and a capsid protein (CP), a conserved nonanucleotide motif on the apex of a putative stem loop structure, and conserved rolling-circle replication and helicase motifs within their likely Rep: all suggesting that they replicate through rolling-circle replication. The Reps and the CPs putatively encoded by these five novel viruses share low to moderate degrees of similarity (22.1 - 44.6%) with other CRESS DNA viruses.
