| Plant samples of jimsonweed (Datura stramonium L.) and thornapple (D. ferox L.) were collected to determine the presence of Cucumber mosaic virus (CMV), Alfalfa mosaic virus (AMV), and Potato virus Y (PVY) in Santiago, Chile (33º34 S lat, 70º38 W long, altitude 625 mosl), using double stranded RNA (dsRNA) analysis and ELISA. Both weeds were positive to the three types of virus with a percentage of infection ranging from 20-30% except for PVY infection in D. stramonium with an incidence of 5%. Under controlled conditions, the aphid Myzus persicae (Sulzer) transmitted CMV from D. ferox to tomatoes (Lycopersicon esculentum Mill.) and sweet peppers (Capsicum annuum L.), but did not transfer it to potatoes (Solanum tuberosum L.). Seeds of positive D.... |
