Abstract

Apple, one of the most important fruit crops world-widely, is required for rapid, cost-effective and sensitive virus detection for its better productivity. RT-PCR is extensively employed for apple virus diagnosis, but the technique requires complete tissue homogenization which is time consuming and laborious. In this study, heating-based RNA extraction method was developed and proven to effectively work for stem tissues slightly better than for leaf tissues. In RT-PCR, almost identical results were generated from the use of RNA extracts from both tissues.

사과는 전 세계적으로 대표적 과수의 하나로서 우량 사과의 생산을 위하여 신속하고 경제적이며 정확한 사과바이러스 진단이 요구되고 있다. RT-PCR은 사과바이러스 진단을 위한 중요한 기술로서 우선 시료조직의 분쇄 및 균질화를 통한 양질의 RNA 추출이 필수적이다. 그러나 분쇄작업은 다량의 시료의 경우 많은 시간과 노동이 요구된다. 본 연구에서는 조직 분쇄과정이 없이 단순 가열에 의한 RNA 추출을 시도하였으며 줄기조직이 잎조직보다 약간 더 적합함을 보여주었다. 그러나 RT-PCR에 의한 사과바이러스 진단에서는 모두 동일한 결과를 나타냈다. 이로써 사과 조직에 대한 단순가열로써 매우 간편하게 양질의 RNA추출이 가능함을 제시하였다.
