Abstract
Banana streak disease is caused by a variety of banana-infecting badnaviruses. A genome of the episomal form of a banana streak MY virus was recovered from an infected banana plant sampled on Vava’u Island, Tonga, and shares >98% pairwise identity with the six other genomes available in public databases.
Highlights
Banana streak disease is caused by a variety of banana-infecting badnaviruses
banana-infecting badnavirus (BIB) exist in two forms, either the infectious episomal form with a circular doublestranded DNA genome, or the endogenous form in which the viral genome is integrated into the host genome
BIBs are able to be spread via infected propagules, and the episomal form is vectored by a number of mealy bug species, including Dysmicoccus brevipes, Planococcus ficus, and Planococcus citri [5,6,7]
Summary
Banana streak disease is caused by a variety of banana-infecting badnaviruses. A genome of the episomal form of a banana streak MY virus was recovered from an infected banana plant sampled on Vava’u Island, Tonga, and shares >98% pairwise identity with the six other genomes available in public databases. BSD is caused by multiple viral species of badnaviruses (genus Badnavirus, family Caulimoviridae). Banana-infecting badnavirus genomes have three open reading frames (ORFs).
