Segment 9 genome maps for six Orbivirus species. Genome maps for segment 9 of the six Orbivirus RefSeqs in GenBank, showing the location of putative ORFX homologues. In SCRV, no long ORF was found in the right location and frame; the two ORFs indicated here are separated by a stop codon. A phylogenetic tree for the six Orbivirus VP6 amino acid sequences (columns with alignment gaps excluded; neighbour-joining tree; numbers indicate bootstrap support [out of 1000]; scale bar represents the number of substitutions per site; tree produced with CLUSTALX [39]) is given at left.
