Notable exception are a group of ampeloviruses with the smallest genomes in the family [e.g. grapevine leafrollassociated virus 4 (GLRaV-4), GLRaV-5, GLRaV-6, GLRaV-9, pineapple mealybug wilt-associated virus 1(PMWaV-1) and PMWaV-3] which do not appear to possess CPm. The genome expression strategy is based on: (i) proteolytic processing of the polyprotein encoded by ORF1a; (ii) 1 Pos. ssRNA ribosomal frameshift for the expression of the RdRp domain encoded by ORF1b, a mechanism not found in other ()RNA plant viruses; (iii) expression of the downstream ORFs via the formation of a nested set of 3 co-terminal sub-genomic RNAs (sgRNAs).	./cache/cord-023770-ymxapsv6.txt	./txt/cord-023770-ymxapsv6.txt
