Species of virus From Wikipedia, the free encyclopedia
Maize white line mosaic satellite virus (syn. Satellite maize white line mosaic virus, Satellite virus of maize white line mosaic virus,[1] SMWLMV, SV-MWLMV) is a plant satellite virus. It is the only species in genus Aumaivirus, which is a member of realm Riboviria without assigned family or order. It only infects maize which is infected by Maize white line mosaic virus (MWLMV) of genus Aureusvirus.[2]

The genus name, Aumaivirus, is a combination of Aureusvirus (the name of the helper virus) and maize, the host plant of the only species of the genus.
SMWLMV has a genome consisting of linear single-stranded RNA of positive polarity. It has a length of 1,168 nucleotides and consists of a single gene that encodes a capsid protein (CP). It neither has a poly(A) tail nor a cap structure. As in satellite tobacco necrosis virus (STNV),[3] the SMWLMV virion is 17 nm in diameter, but the capsid protein has limited sequence homology with the corresponding proteins of STNV viruses.[2][4]
