Nucleotide sequence of the 30K protein cistron of cowpea strain of tobacco mosaic virus

Abstract
The nucleotide sequence of cloned cDNA copies of cowpea strain of tobacco mosaic virus RNA including the 30K protein cistron was determined. The 30K protein cistron was located at residue 676-1,527 from the 3′ end of the genomic RNA. The 30K protein was composed of 282 araino acid residues and was basic, similar to the 30K protein of common strain OM. However, homology of the amino acid sequences between the two strains was only 27%.
