Abstract

In the present study, we performed the PCR assay using TOX2P/TOX2M primer targeting a specific region within mcyB gene to identify potential microcystin-producing cyanobacteria. TOX2P/TOX2M primer set was effective in amplifying mcy gene in the field samples containing Microcystis spp. of 1,000 cells per mL. Moreover, the results from the PCR assay agreed with those of the ELISA analysis. Consequently, this study demonstrated that TOX2P/TOX2M primer set can be used as a genetic probe for the early detection of cyanobacterial toxigenicity in Korean water bodies.

남조류의 독성 잠재력을 확인하기 위해 microcystins 합성 유전자인 mcyB에 특이적으로 작용하는 TOX2P/TOX2M primer쌍을 이용한 whole-cell PCR을 실시하였다. 환경시료를 대상으로 한 실험 결과에서 TOX2P/TOX2M primer쌍은 약 1,000 $cells{\cdot}mL^{-1}$의 낮은 밀도에서 효과적으로 mcyB 유전자의 증폭에 성공하였으며, mcyB유전자를 지닌 종들은 모두 ELISA분석에 의해 microcystins의 생성이 확인되었다. 따라서, TOX2P/TOX2M primer쌍은 국내의 수체에서 독성 남조류의 신속하고 효과적인 검출을 위한 유용한 probe로 판단되었다.
