Genomic components of the begomovirus causing yellow mosaic disease (YMD) in soybean in Delhi were cloned, sequenced and infectivity proved. Nucleotide sequence analysis of the virus isolate revealed more than 89% identity with Mungbean yellow mosaic India virus (MYMIV) and therefore it is designated as soybean isolate of MYMIV (MYMIV-[Sb]). Total nucleotide and predicted amino acid sequence an...

Monoclonal antibodies were obtained against Tomato mosaic tobamovirus (ToMV) isolated in Brazil. One antibody (8G7G2) isotyped as IgG2b (κ light chain) showed strong specificity and very low cross reaction with the Tobacco mosaic virus (TMV). It can be used in identification of tomato mosaic virus (ToMV).

Since the isolation of tobacco mosaic virus in the form of a characteristic, crystalline material of high molecular weight (1, 2), a wealth of experimental data has been accumulated (3-7) which indicates that tobacco mosaic virus is, in fact, a nucleoprotein, the molecules or particles of which are 15 by 280 rnp in size, with an anhydrous weight approximately 40 million times that of the hydrog...
