General DescriptionThe genus Lolavirus is one of the genera in the family Alphaflexiviridae. In genome organisation and phylogenetic analysis its single member particularly resembles viruses in the genus Potexvirus but the virions are longer, the coat protein is larger and there is probably a small additional ORF6. Its name is derived from the type species Lolium latent virus.
MorphologyVirions filamentous, not enveloped, c. 640 nm long and 13 nm in diameter.
GenomeMonopartite, linear, single stranded, positive-sense RNA, c. 7700 nucleotides long. The 3' terminus has a poly(A) tract.
Genus Genomic OrganizationThere are a 5, or more likely 6, open reading frames, probably translated by means of subgenomic RNAs.
Type Member Genomic OrganizationThere are 6 predicted open reading frames, probably translated by means of subgenomic RNAs:
|2||30 kDa||ORFs 2-4 (Triple gene block): |
translated from different reading frames
and all involved in cell-to-cell movement
|5||32 kDa||Coat protein|
|6||5 kDa||Probable nucleic acid binding protein (NABP)|
