Fig. 2.
Genome characteristics and mutation patterns of HCoV-229E and related viruses from animals. (A) Maximum-likelihood phylogeny of complete genomes of representative HCoV-229E-related coronaviruses from humans, camelids, and bats. Filled circles at nodes indicate bootstrap supports of 100% (200 replicates). HCoV-NL63 GenBank (accession no. NC_005831) was used as an outgroup (branch truncated). (B) Genomic organization of 229E-related coronaviruses. Regions with deletions are given in red. (C and D) Deletion patterns in ORF 8 homologs of 229E-related coronaviruses regions with deletions are given in red (numbered I–IV). Asterisks represent triplets that would act as in-frame stop codons; arrows represent possible start codons.
