title: Nucleotide sequence of the coat protein cistron and the 3' noncoding region of cucumber green mottle mosaic virus (watermelon strain) RNA.
abstract: Double-stranded cDNA copies of cucumber green mottle mosaic virus (watermelon strain, CGMMV-W) RNA polyadenylated in vitro were cloned into the pBR322 at the PstI site. The sequence of 1071 nucleotides from the Tend of the genomic RNA was determined using two recombinant plasmids and the genomic RNA. The coat protein cistron was located in residues 176-661 from the 3' end. The coat protein was composed of 160 amino acid residues with the molecular weight of 17,261. The 3' noncoding region of the CGMMVW genome was 175 nucleotides long and highly homologous to that of the common strain of TMV. The assembly origin of reconstitution is positioned within the coat protein cistron as predicted previously. In the 5' flanking region of the coat protein cistron a long open frame, probably of 30K protein, was found. The predicted 30K and the coat protein cistron would overlap each other as is the case of the cowpea strain of TMV.
