Immunosorbent electron microscopic studies on a tobamovirus causing brinjal necrotic mosaic.

Serological relationships of brinjal necrotic mosaic virus (BNMV), a strain of tobacco mosaic virus (TMV) causing necrotic mosaic disease of brinjal in India to other TMV strains was investigated by immunosorbent electron microscopy (ISEM). The intensity of trapping and decoration revealed a close relationship of BNMV to TMV-D, TMV-U1 and TMV-WU1 strains, and a distant relationship to TMV-A1 and TMV-P11 strains. There was a negligible relationship to TMV-P14, tomato mosaic virus (ToMV) and cucumber green mottle mosaic virus (CGMMV). Therefore, BNMV is proposed to be distinct from the previously reported TMV-A1 strain of brinjal.
