The Cloning and Sequencing of Read-through Protein Gene from BYDV-GAV Virus

摘要

The cDNA of BYDV-GAV read-through protein (RTP) 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 was determined by dideoxynucleotide chain-termination method. The BYDV-GAV RTP gene consists of 1377nt. Its sequences were most similar to that of the RTP gene of BYDV - MAV with identities of 87.4% and 87.1% at the nucleotide and amino acid levels, respectively.
