Nucleotide sequence of the coat protein coding region of tulip breaking virus
1Faculty of Agriculture, University of Tokyo, Japan.
Abstract:
cDNA of tulip breaking virus-tulip (TBV-tulip) RNA was synthesized and cloned in E. coli. One clone that contains a 4.5 kb insert was identified by restriction enzyme analysis, dot immunobinding assay (DIBA), and partial sequencing. Then 1479 nucleotides of the 3'-terminus of the clone were sequenced and revealed that the sequence contains one open reading frame (ORF), followed by an untranslated region of 255 nucleotides and a poly(A) tract. The deduced amino acid sequence was found to include the C terminus of the predicted RNA-dependent RNA polymerase and the coat protein. A glutamine-alanine dipeptide was identified as a putative NIa protease cleavage site at the N terminus of the coat protein.
