Properties and host range of turnip crinkle, rosette and yellow mosaic viruses

Three isolates of turnip yellow mosaic virus and two other flea-beetle transmitted viruses, turnip crinkle and turnip rosette, have many similar properties : thermal inactivation end-point between 80 and 90 degrees C.; dilution end-point greater than 10(-4); longevity in vitro at about 20 degrees C. at least 30 days. All were transmitted by mechanical inoculation to a wide range of cruciferous host plants, including many weeds. Turnip yellow mosaic virus infected only Reseda odorata outside the Cruciferae, whereas rosette virus infected a few and crinkle virus many non-cruciferous hosts. RESP-4038
