First detection of five previously unreported grapevine viruses in Australia

This is the authors' abstract. We don't add key points for this paper.

Five grapevine viruses, including grapevine geminivirus A (GGVA), grapevine Syrah virus 1 (GSyV-1), grapevine Cabernet Sauvignon reovirus (GCSV), grapevine virus F (GVF) and grapevine Red Globe virus (GRGV) have been detected in four South Australian vineyards using metagenomic high throughput sequencing for the first time in Australia. Most of them were present in asymptomatic grapevines and some were present in grapevines with leafroll disease that were infected by several other viruses, including grapevine leafroll-associated viruses. Therefore, the association of GGVA, GSyV-1, GCSV, GVF and GRGV with disease in Australia is unknown.
