Interpretive Summary:

Technical Abstract: More than 700 soybean plant introductions were inoculated with tobacco ringspot virus (TRSV) in the greenhouse. All the introductions were susceptible to the virus, while about 15% had mild symptoms. All the resistant soybean lines previously reported were susceptible to the virus. Three TRSV isolates were inoculated on 18 selected soybean lines in the field. Two of the three isolates caused severe symptoms and a reduction in seed production. ELISA tests indicated that virus concentrations were almost the same in all of the plants infected by three different isolates suggesting that the symptom severity was not correlated to virus concentration. Twelve plant species were inoculated with two strains of TRSV. Most were susceptible including Arabidopsis thaliana. Two species, Raphanus sativus and Brassica rapa were not infected.
