Taxonomic structure of the family.
Virions contain one molecule of linear positive-sense single stranded RNA.
Total genome length is 9700-11800 nt. The 5' end of the genome has a cap. 3' end has a poly(A) tract.
Virus infects vertebrates and plants.
Virions tightly enveloped (by a lipid membrane); slightly pleomorphic; spherical; 70 nm indiameter. Surface projections of envelope distinct; glycoprotein spikes (composed of twovirus proteins forming heterodimers). Nucleocapsids isometric; 40 nm in diameter. Symmetry icosahedral (T=4).
