Canna yellow streak virus: a new potyvirus associated with severe streaking symptoms in canna

A new potyvirus has been found in canna. A 1700-nucleotide region at the 3' end of the genomic RNA has been sequenced from two isolates. The sequence reveals the virus to be a distinct member of the genus Potyvirus but most closely related to Johnsongrass mosaic virus. A specific primer pair wa...

Description
Summary:A new potyvirus has been found in canna. A 1700-nucleotide region at the 3' end of the genomic RNA has been sequenced from two isolates. The sequence reveals the virus to be a distinct member of the genus Potyvirus but most closely related to Johnsongrass mosaic virus. A specific primer pair was designed that enabled canna material to be screened specifically for this virus. The virus was consistently found in cannas showing severe virus symptoms. This virus has been found in different canna varieties from the UK, Belgium, Netherlands, France and Israel. The name Canna yellow streak virus (CaYSV) has been proposed for this new virus.
