| Abstract:
During systematic screening for virus infection of plum plantations in Hungary a tobamovirus was isolated in 1978. It was compared to five other serotypes of tobacco mosaic and tomato mosaic viruses (TMV-U1 and ToMV-L/DH, U2, C 13, Sd) isolated previously from different host plants. The comparison was carried out by using a limited host range. To determine the degree of relationship among tobamovirus strains the homologous and heterologous titres of antisera were established and the SDI-values were calculated. Antisera of each serotype were cross absorbed in succession with the heterologous antigens, then were investigated for their reactivity. 16 antibody groups were established by using immuno-absorption tests. TMV isolate from plum was identical with the TMV-U1 strain in respect of their serological properties, however they slightly differed in their symptomatology. | |
