General Description

This family is distinctive for its isometric particles of 25-30 nm diameter, monopartite genome and persistent, aphid transmission. The viruses often cause yellowing symptoms in their plant hosts.

Morphology

Virions are isometric (icosahedral), not enveloped, 25-30 nm in diameter, with 32 capsomeres per nucleocapsid. They contain 28 % nucleic acid.

Genome

Monopartite, linear, single-stranded RNA, 5300-5800 nucleotides long. The 5'- terminus sometimes has a genome-linked protein (VPg).
