Asystasia mosaic Madagascar virus: A novel bipartite begomovirus infecting the weed Asystasia gangetica in Madagascar

De Bruyn A., 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. (Résumé d'auteur)
