Zusammenfassung:PURPOSE: Specific primers for detecting cucumber green mottle mosaic virus are provided, thereby increasing the detection limitation and sensitivity about 1,000 times higher than using antiserum, detecting all kinds of cucumber green mottle mosaic virus, and improving the detection accuracy by removing nonspecific reaction with other related viruses. CONSTITUTION: The specific primers for detecting cucumber green mottle mosaic virus comprise a nucleic acid fragment selected from the nucleotide sequences set forth in SEQ ID NO: 2 to SEQ ID NO: 4 which species specifically bind with cucumber green mottle mosaic virus, complementary nucleotide sequences thereof, and mutated nucleotide sequences thereof; and another nucleic acid fragment selected from the nucleotide sequences set forth in SEQ ID NO: 7 to SEQ ID NO: 9 which are combined with the selected nucleic acid and species specifically bind with cucumber green mottle mosaic virus, complementary nucleotide sequences thereof, and mutated nucleotide sequences thereof, wherein the mutation is selected from deletion of base, addition of base, substitution of base or the combination thereof. 본 발명은 오이녹반모자이크바이러스와 종 특이적으로 반응하는 핵산단편에 관한 것으로, 보다 상세하게는 서열번호 2 내지 4 및 7내지 9로 표시되는 염기서열, 그의 상보적인 염기서열 또는 이들 염기서열에 의거한 변이가 실시된 변형서열의 어느 하나의 핵산단편 또는 이들 핵산 단편의 특정 조합으로 구성되는 프라이머를 개시한다. 본 발명에 의하면 항혈청을 이용한 진단방법보다 1,000배 이상 검출한계가 높으며, 지금까지 알려진 오이녹반모자이크바이러스의 모든 계통에 대한 검출이 가능하다. 또한 박과작물에 발생하는 다른 관련 바이러스와의 비특이적 반응이 없어 훨씬 정밀하게 오이녹반모자이크바이러스의 감염여부를 진단할 수 있다.
