New host-virus relations between different Solanum species and viruses.
We have studied the susceptibility or resistance of Solanum capsicastrum Link. et Schauer, S. comatum Sendt., S. dulcamara L., S. luteum Mill., S. malacoxylon Sendt. and S. nigrum L. to three aphid transmissible viruses [alfalfa mosaic alfamovirus (AMV), potato M. carlavirus (PVM) and potato S carlavirus (PVS)]. Out of the species, S. capsicastrum, S. comatum, S. dulcamara, S. malacoxylon and S. nigrum to AMV, S. capsicastrum and S. malacoxylon to PVM and S. capsicastrum, S. luteum and S. nigrum to PVS showed the highest resistance (immunity). Symptoms could not be seen on inoculated plants and the virus could be detected by them neither by serological nor biological tests. Solanum luteum plants were susceptible to AMV. Solanum comatum, S. dulcamara, S. luteum and S. nigrum showed susceptibility to PVM. Solanum comatum and S. dulcamara were susceptible to PVS. Symptoms (necrotic lesions, mosaic and chlorosis) could be seen after inoculation and the absorbance values (DAS-ELISA) exceeded twice that of the healthy control samples during the serological tests.
