Asystasia mosaic Madagascar virus: A novel bipartite begomovirus infecting the weed Asystasia gangetica in Madagascar
Harimalala M.A., Hoareau M.M., Ranomenjanahary S., Reynaud B., Lefeuvre P., Lett J.M.. 2015. Archives of Virology, 160 (6) : p. 1589-1591.
Here, we describe for the first time the complete genome sequence of a new bipartite begomovirus in Madagascar isolated from the weed Asystasia gangetica (Acanthaceae), for which we propose the tentative name asystasia mosaic Madagascar virus (AMMGV). DNA-A and -B nucleotide sequences of AMMGV were only distantly related to known begomovirus sequence and shared highest nucleotide sequence identity of 72.9 % (DNA-A) and 66.9 % (DNA-B) with a recently described bipartite begomovirus infecting Asystasia sp. in West Africa. Phylogenetic analysis demonstrated that this novel virus from Madagascar belongs to a new lineage of Old World bipartite begomoviruses.
