TMV외피 단백질 유전자의 연초로의 형질전환
Tobacco plant transformed with a coat protein gene sequence of TMV
초록
A double - stranded cDNA fragment (436bp) encoding coat protein of tobacco mosaic virus(TMV) was derived from the total 480nucleotides gene after reverse transcription of TMV RNA, and subclorled into a plant expression vector pBl 121, resulting in pBL 430. The plasmid DNA containing this chimeric gene was moved from E. cofi to Agrobacterium tumefaciens strain A28l, and was introduced in시 the tobacco plant by the Agrobocterium Ti - mediated transformtion system. The transformants were selected on a selection media containing kanamycin. The shoots add roots could be differentiated from the explants and whole plants were obtained. From Southern blot hybridization analysis, DNA extracted from transformants, it could be conformed that the chimeric gene fragment was inserted into the genomic DNA of tobacco plant.
