First report of chrysanthemum stunt viroid isolated from potato (Solanum tuberosum) plants in Russia

Abstract

A pospiviroid, detected from asymptomatic potato plants (Solanum tuberosum) from Russia, was identified as chrysanthemum stunt viroid (CSVd). The genomic sequence of this potato isolate showed 100% identity with that of the chrysanthemum isolates from Japan. The CSVd RNA transcribed from the cDNA, having the sequence of the isolate from Russia, was able to infect potato, tomato, and chrysanthemum plants. The infected chrysanthemum plants exhibited stunting symptom. This is the first report of the occurrence of CSVd in Russia, its natural infection of potato plants and the potential spread of CSVd through propagation of infected potato.
