FIG. 6.

A gallery of views of virus structures, including insect members of the picornavirus superfamily, definitive picornaviruses, and other insect viruses. In each case, the rendered surface of the structure (at an 18-Å resolution) is shown, as well as a central section through the map. The masses marked are those of the atomic structures shown at lower-resolution density here, except for KFV, which is a mass value based on its capsid surface volume normalized to the mass/volume ratio of the other structures (see Fig. 5). The viruses shown are Galleria mellonella densovirus (GmDNV) (a parvovirus with a T=1 capsid; total genome size, 5 kb [53]); tobacco ringspot virus (TRSV) (a nepovirus with one coat protein making a pseudo T=3 capsid; total genome size, 15.5 kb [8]); adeno-associated virus (AAV) (with a T=1 capsid [65]); bean pod mottle virus (BPMV) (a comovirus with two coat proteins making a pseudo T=3 capsid; total genome size, 9.7 kb [41]); FMDV (a classical picornavirus with a pseudo T=3 capsid; total genome size, 8.4 kb [1]); KFV (total genome size, 11 kb); CrPV (a pseudo T=3 virus; total genome size, 9.2 kb [56]); Pariacoto virus (PaV) (a nodavirus with a T=3 capsid; total genome size, 4.3 kb [55]); and Norwalk virus (NV) (a calicivirus with a proper T=3 capsid; total genome size, 7.9 kb [9, 49]).
