Abstract

Immunocapture reverse transcription polymerase chain reaction (IC-RT-PCR) was applied to the detection of Cucumber green mottle mosaic virus (CGMMV), Kyuri green mottle mosaic virus (KGMMV), and Zucchini green mottle mosaic virus (ZGMMV) on Cucurbitaceae crops. These seed-borne tobamoviruses were accurately detected from the infected leaves and seeds by IC-RT-PCR. This method was estimated to be about 100 times more sensitive than ELISA, and also it allowed the direct confirmation of ELISA results by using the captured antigens from a completed ELISA microwell. This convenient and reliable method could be used routinely for large-scale field surveys or seed tests of Cucurbitaceae crops.

박과작물에 발생하는 종자전염 바이러스 3종(CGMMV, KGMMV, ZGMMV)에 대한 검출을 위해 IC-RT-PCR의 적용 가능성을 시험하였다. IC-RT-PCR을 이용하여 감염 종자와 잎으로 부터 바이러스의 특이적인 검출이 가능하였으며, 검출 민감도는 ELISA 보다 100배 이상 높았다. 또한 반응을 마친 ELISA 마이크로플레이트에 남아있는 항원을 IC-RT-PCR의 template로 사용할 경우 ELISA 결과를 곧바로 확인할 수 있었다. 따라서 IC-RT-PCR에 의한 본 검정방법은 박과작물의 대규모 포장검사 및 종자검사에 편리하게 사용될 수 있을 것으로 기대된다.
