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

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 Asia, and have not been observed in Africa far. A tobamovirus isolate infecting a wild Coccinia grandis plant was collected central Sudan 2012. Its host range appeared be limited cucurbits. full-length genome sequence determined found 85% identical those of isolates fruit (CFMMV) described Israel Korea, whereas the aa identity CFMMV 92 95%, depending on protein. Based its biological molecular properties, we suggest that Sudanese should considered divergent CFMMV. This first description Africa. high divergence from Korea suggests lack recent exchanges between other populations.
