FIG 2.
Genome organization of members of Deltacoronavirus. Open reading frames downstream of spike (S) gene are magnified to show the differences among the genomes of the 10 CoVs. Papain-like protease (PLpro), chymotrypsin-like protease (3CLpro), and RNA-dependent RNA polymerase (RdRp) genes are represented by green boxes. S, envelope (E), membrane (M), and nucleocapsid (N) genes are represented by orange boxes. Putative accessory proteins are represented by blue boxes. The novel coronaviruses discovered in this study are shown in bold. Abbreviations for the viruses are the same as those in Fig. 1.
