It was revealed that 55°C gave the best result in terms of producing exactly the expected fragment (1044 bp) from as many samples as possible although accompanied by few fade non specific fragments. However, by application of “hot-start” PCR and annealing at 60°C the specific fragment was amplified from 41 out of 86 samples. This was the first amplification of the precise MP cDNA from GFLVs in Iran which is very important as to preparation of recombinant anti-GFLV MP antibody to use in studying the GFLV- grapevine interaction, and also for generating pathogen-derived resistant vines.}, keywords = {Annealing,degenerate,GFLV,MP,Hot-start,PCR}, url = {https://www.ijbiotech.com/article_7088.html}, eprint = {https://www.ijbiotech.com/article_7088_93de595966edf639c544af32ce3fad1f.pdf} }
