Abstract
When the first red tide alert by Cochlodinium polykrikoides was alarmed around the Oenarodo coast on Aug. 27, 1997, there co-occurred two chain-forming naked dinoflagellates which were different sized but looked fairly similar. The analyses of 24S rRNA sequences of these species showed that their gene sequences had only 74.9% identity. This low value implies that they are quite different species. After isolation and cultivation of each species, the morphological characteristics were observed. This revealed that the larger species ranging from 20 to 35
1997년 8월 27일 전남 고흥군 외나로도 연안에 그 해 최초로 Cochlodinium polykrikoides에 의한 적조경보 발령시, 동 해역에는 형태상으로 유사하지만 크기가 다른 연쇄상의 무각 와편모조류가 공존하고 있었다. 이들의 24S rRNA 유전자 엽기서열을 분석한 경과, 염기서열의 상동성은 74.9%에 불과하여 두 총은 상이한 종인 것으로 드러났다. 또한 각 종을 분리, 배양하여 형태상의 특성을 비교 관찰한 결과, 20~35
