CLONING AND SEQUENCING OF COAT PROTEIN GENE FROM BARLEY YELLOW DWARF VIRUR GAV VIRUS
摘要The Barley yellow dwarf virus (BYDV) GAV isolate was preserved at the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences. The cDNA of BYDV GAV coat protein (CP) gene was amplified from the extracted RNA of BYDV GAV by using the polymerase chain reaction (PCR), and cloned into pGEM-7zf(+). Its complete nucleotide sequence has been determined by means of Sanger's dideoxy-mediated chain-termination method. The result showed that BYDV GAV CP gene has 600nt. It shares 97.5% and 96.5% identity with CP gene of BYDV MAV-PS1 in terms of nucleotide and amino acid sequences respectively.
