  • 시판고추 종자로부터 Tobamovirus를 검출하고 Tobamovirus 오염률을 조사하고자 gelatin particle agglutination test (GPAT)의 최적조건을 조사하였다. Gelatin 입자에 감작할 담배 모자이크 바이러스 고추 계통에 대한 ${\gamma}$-globulin G 의 최적농도는 100$\mu\textrm{g}$/$m\ell$이었고, GPAT의 바이러스 검출 감도는 효소면역항체법 및 dot immuno-binding assay와 유사하였으며, Tobamovirus 검출을 위한 종자시료의 최적 희석배수는 5배에서 25배였다. 그리고 최적화된 GPAT에 의한 국내시판 고추종자의 Tobamovirus 오염률은 평균 79.1%인 것으로 판명되었다.

  • Gelatin particle agglutination test (GPAT) was used to detect Cymbidum mosaic virus (CymMV) in Cattleya plants. Gelatin particles were coated with purified anti-CymMV immunoglobulin of 25-100 $\mu\textrm{g}$/ml and were subjected to several different concentrations of purified CyMfV as well as varying dilutions of orchid leaf extracts. The GPAT detected purified CymMV up to a minimum concentration of 10 $\mu\textrm{g}$/ml. CymMV was detected from crude sap extract of infected Cattleya leaves and roots up to 1:51,200 and 1:25,600 dilutions, respectively. However, the optimum range of leaf and root sap dilutions was between 50-100. Non-specific reactions were not encountered from any of the healthy orchid plants tested. The entire GPAT process was completed within 2-3 hours. This test was found to be very useful for the detection of CymMV in orchids because it is sensitive, economical, and easy to perform.
