Molecular Coning of cDNA for Garlic Mosaic Virus Genome
마늘 모자이크 바이러스 게놈에 대한 cDNA의 클로닝
Abstract
Potyvirus group is the largest group among plant virus groups and damages severely plant hosts upon infectiQn. In order to investigate the mechanism by which potyviruses induce disease in plants, a cDNA clone 29-6 which is cOIlsidered to be a cDNA clone for garlic mosaic virus (GMV) was isolated. It did not hybridize to garlic latent virus genome, which is one of two major garlic viruses. Northern blot analysis shows that the genome size of garlic mosaic virus was about 9 kb. Clone 29-6 strongly hybridizes to poly(A) RNA isolated from garlic leaves, suggesting that GMV RNA is polyadenylated as other potyviruses. Nucleotide sequence analysis of cDNA clones overlapping with clone 29-6 showed that garlic plants are infected with various strains of garlic mosaic virus which are closely related to each other. other.
Potyvirus group에 속하는 것으로 알려진 마늘 모자이크 바이러스 (GMV)가 식물에서 병을 유도하는 메카니즘을 이해하기 위하여, 마늘에 존재하는 GMV에 대한 cDNA clone인 clone 29-6을 분리하였다. Northern blot 분석에 의해 이 바이러스의 genome size는 약 9 kb이고, 또한 clone 29-6은 GLV genome과 유사성이 없었으며, 마늘잎으로부터 분리된
