Alternanthera mosaic virus (AltMV) is a plant pathogenic virus. AltMV belongs to the virus genus Potexvirus and the virus family Alphaflexiviridae.
AltMV was first identified in 1999 in Queensland, Australia.[1] The virus was found in Alternanthera pugens(Amaranthaceae), a weed found in both the southern USA and Australia. Since then, AltMV has been identified in various ornamental plants in Italy,[2] the United States (Maryland and Pennsylvania,[3] Florida,[4] and New York),[5] and Brazil.[6]
This virus has a close serological relationship (ELISA/antiserum to the capsid protein) with another well known Potexvirus called Papaya mosaic virus (PapMV). This relationship has led to several examples of misdiagnosis in the past.[7][8] Sequencing has shown that the core region of the capsid protein is only 79.8% identical to PapMV at the nucleotide level.[1] Isolates of AltMV have shown a 93-99% nucleotide identity to the original Australian isolate.[2][3][4]
