초록

시스트와 영양세포의 유연성을 파악하기 위해 발아실험을 실시하였다. 발아실험 결과 총 25종에서 발아가 이루어져 시스트와 영양세포와의 관계를 확인하였다. 가막만에서 우점종으로 출현하지만 영양세포로 출현이 제한적인 Protoperidinium americanum이 발아실험 결과 확인되었고, Protoperidinium oblongum의 시스트로 알려진 Votadinium carvum은 발아실험 결과 세 가지 형태의 시스트에서 각기 다른 영양세포가 출현하여, 유전자 분석 등을 통한 정확한 종 동정이 요구되었다. 또한 Cochlodinium polykrikoides의 시스트라고 알려진 종은 발아실험 결과 C. polykrikoides의 시스트가 아닌 Cochlodinium sp.인 것으로 판명되었고 C. polykrikoides의 시스트는 출현하지 않았다.

This study examined the relationship between dinoflagellate cysts and vegetative cells, to a certain extent, by conducting a germination experiment on dinoflagellate cysts collected from a sediment trap and surface sediment. The germination experiment showed that 56.8%, 25 of the 44 species of dinoflagellate cysts seen in the sediment trap, germinated, which confirmed the relationship between cysts and vegetative cells. The germination experiment also found that Votadinium carvum showed different forms of vegetative cells in all three forms of cysts, which required an accurate identification of the species through a genetic analysis. Furthermore, the species known to be the cyst of Cochlodinium polykrikoides was determined to be Cochlodinium sp., and the cysts of C. polykrikoides did not appear.
