First report of Andean potato latent tymovirus in Ullucus tuberosus
Ulluco (Ullucus tuberosus) is an Andean tuber crop often cultivated ;in close association with native potato cultivars. An isolate of Andean potato latent tymovirus (EPPO A1 quarantine pest) has been detected in several ulluco accessions, originating from Peru, Bolivia, Colombia and Argentine and maintained in in vitro conditions at the International Potato Center. This is the first report of Andean potato latent tymovirus in Ullucus tuberosus. The authors felt that this gives support to the proposition that plant viruses can adapt to new hosts subsequent to long-term associations.
