Abstract
An isometric virus associated with a rosetting disease of peach in Northern Italy was identified as strawberry latent ringspot virus (SLRV). Host range and pathogenicity on herbaceous plants suggested a closer similarity to the type strain of SLRV than to a raspberry isolate, recently described by our laboratory.
The virus was purified from Chenopodium quinoa using clarification with butanol-chloroform, precipitation with polyethylene glycol and differential centrifugation.
Two components were observed by electron microscopy, density gradient centrifugation and polyacrylamide gel electrophoresis.
Two kinds of proteins were detected with molecular weights of 29,000 and 44,000. Serological differences with our raspberry isolate of SLRV were also.
