Transgenic Tobacco Plants Introduced with cDNA of Cucumber Mosaic Virus Satellite RNA
오이 모자이크 바이러스 위성RNA의 cDNA가 도입된 형질전환 담배의 육성
Abstract
The cDNA of CMV-As satellite RNA was introduced into tobacco plants (Nicotiana tabacum cv. Samsun NN) using a binary Ti plasmid vector system of Agrobacterium tumefaciens. The cDNA of satellite RNA introduced into tobacco plants was detected by polymerase chain reaction (PCR) and molecular hybridization analyses. Symptom development was distinctly suppressed in the transgenic tobacco plants when inoculated with CMV-Co. CMV concentration in the transgenic tobacco plants was decreased to 1/40 of non-transgenic tobacco plants. The kanamycin resistance gene of the transgenic tobacco plants was also detected in the progeny.
