Abstract

In this paper, we report a characterization of Prunus necrotic ringspot virus (PNRSV) isolate. The virus was identified from 'Yumyeong' peach showing mild mosaic on leaves in commercial orchard of 'Umsung', Chungbuk province in Korea. The virus isolate produced ringspot symptom on the inoculated cotyledons and systemic mosaic and malformation on the upper leaves of Cucumis sativus. Systemic mottles were appeared in Chenopodium quinoa. When the buds of the virus infected stem were grafted on the healthy young Prunus persica GF305 seedlings, line pattern with mosaic appeared within 3 months. Isometric virus-like particles were found in parenchyma cells and plasmodesmata of C. sativus leaves inoculated mechanically with the virus. The cDNA fragments of PNRSV coat protein (CP) region, approximately 675bp, were synthesized from genomic RNA extracted from virus-infected leaves by RT-PCR using specific primer pairs. Partial nucleotide sequences of the CP regions were determined and analyzed with the known PNRSV. The CP gene of PNRSVKorea isolates showed 93.9~94.7% similarity to the 4 known PNRSV isolates.

국내의 복숭아 과수원 중에 충북 음성지역의 유명 품종에서 약한 모자이크증상 잎으로부터 Prunus necrotic ringspot virus (PNRSV)를 분리 동정하였다. 지표식물을 이용한 생물검정에서 Cucumis sativus의 접종 자엽에 원형모양의 반점이 관찰되었으며 상엽으로 전이되어 모자이크와 잎기형 증상을 나타내다가 고사하는 것으로 나타났다. 접종한 Chenopodium quinoa 접종엽과 상엽에도 모틀증상을 나타내었다. 목본 지표식물 Prunus persica GF305를 활용한 검정에서는 바이러스 감염된 줄기의 눈을 인위적으로 접종한 지 3개월 후에 잎에 라인 패턴의 모자이크 증상을 관찰할 수 있었다. 인위접종한 Cucumis sativus 잎조직의 세포 검경에서 parenchyma cells과 plasmodesmata 내에 존재하는 구형 바이러스 입자가 관찰되었다. PNRSV의 외피단백질 유전자 분석을 위해 RT-PCR 진단 프라이머와 조건을 설정하고 분석한 결과 675bp 위치에서 특이적으로 증폭된 것을 확인할 수 있었다. 또한 증폭산물을 회수하여 염기서열 분석한 결과 기 보고된 4개의 PNRSV isolate와 93.9~94.7%의 유전적 상동성을 보였다. 결론적으로 복숭아 과수원에서 분리한 바이러스주의 생물적 특성과 유전자 분석결과를 종합하여 Ilarvirus에 속하는 PNRSV인 것으로 최종 동정하였다.
