The genomic context of the intein-coding sequence in Phytophthora ramorum. The diagram depicts the structures of contigs 4, 5 and 6 of scaffold 19 of the assembled P. ramorum genome sequence. ORFs are represented by the shaded boxes. Blue-shaded boxes represent ORFs having a high quality match (E<1 × 10-30) in the assembled Phytophthora sojae genome sequence (see 4). Red-shaded boxes represent ORFs whose best matches among all the protein sequences in GenBank are proteins coded by African swine-fever virus (4). The intein and associated RNA polymerase are represented by ORFs 6, 7 and 8 of contig 5. ORFs are as determined by the ORF finder program http://www.ncbi.nlm.nih.gov/gorf/gorf.html webcite, except ORF1 of contig 4, which was extended back to the previous stop codon. Contig 6 extends further than the sequence depicted here.
