Abstract:
Canna yellow streak virus (Potyvirus, Potyviridae) was sequenced using the novel method of next-generation pyrosequencing. The complete genome was found to be 9,502 nucleotides excluding the poly-A tail with a predicted genome organisation typical for a member of the genus Potyvirus. As with other potyviruses that infect monocotyledons, some of the predicted cleavage sites of the polyprotein genome were unusual, such as a glutamic acid/threonine (E/T) between the CI and 6K2 proteins and a glutamic acid/aspartic acid (E/D) between the NIa and NIb proteins. Evidence of the presence of endogenous pararetroviruses in the canna genome was found from the large number of sequences obtained with this method.
