Detection and complete genome sequence of a divergent isolate of cucumber fruit mottle mosaic virus on Coccinia grandis in Sudan

Abstract : Cucurbit-infecting tobamoviruses known so far belong to six acknowledged or tentative species. Except for cucumber green mottle mosaic virus (CGMMV), which is present worldwide, they are geographically restricted, mostly to Asia, and have not been observed in Africa so far. A tobamovirus isolate infecting a wild Coccinia grandis plant was collected in central Sudan in 2012. Its host range appeared to be mostly limited to cucurbits. Its full-length genome sequence was determined and found to be 85% identical to those of isolates of cucumber fruit mottle mosaic virus (CFMMV) described in Israel and Korea, whereas the aa sequence identity to CFMMV isolates was 92 to 95%, depending on the protein. Based on its biological and molecular properties, we suggest that the Sudanese isolate should be considered a divergent isolate of CFMMV. This is the first description of CFMMV in Africa. Its high divergence from isolates from Israel and Korea suggests a lack of recent exchanges between CFMMV from Sudan and the other known populations.
