The complete nucleotide sequence of a new bipartite begomovirus from Brazil infecting Abutilon

The complete nucleotide sequence of Abutilon mosaic Brazil virus (AbMBV), a new bipartite begomovirus from Bahia, Brazil, is described and analyzed phylogenetically. Its DNA A is most closely related to those of Sida-infecting begomoviruses from Brazil and forms a phylogenetic cluster with pepper- and Euphorbia-infecting begomoviruses from Central America. The DNA B component forms a cluster with different Sida- and okra-infecting begomoviruses from Brazil. Both components are distinct from those of the classical Abutilon mosaic virus originating from the West Indies. AbMBV is transmissible to Nicotiana benthamiana and Malva parviflora by biolistics of rolling-circle amplification products and induces characteristic mosaic and vein-clearing symptoms in M. parviflora.
