| 英文摘要 | The parasitic dinoflagellates in the genus of Amoebophrya can infect broad ranges of planktonic dinoflagellates, and transform algal biomass into organic matter that can be recycled within the planktonic community. The ecological significance of Amoebophrya spp. during harmful algal bloom (HAB) events was gradually recognized along with revelation of its host specificity and diversity in picoplankton communities. The eutrophicated coastal waters of China are frequently affected by HABs, particularly in Changjiang (Yangtze River) estuary and the adjacent East China Sea; while, no research has been conducted to explore the ecological roles of parasitism during HAB events and the related dinoflagellate bloom dynamics. For the first time, we confirmed the presence of Amoeboptaya infections in the planktonic community of this region; six species of dinoflagellates were infected, including Ceratium tripos, Scrippsiella trochoidea, Gonyaulax sphnfera, Gymnodinium sp., Gonyaulax sp. and an Alexandrium sp. Molecular sequences retrieved from environmental water samples revealed high genetic diversity of Amoebophryidae-like organisms in the water column. Amoebopluya-infected dinoflagellates were only observed in high salinity (>20) stations suggesting that salinity may be a factor limiting the distribution of Amoebophyra infections in natural environment. Whereas, no evidence of Amoebophiya infection was observed in the bloom-forming species Karenia mikimotoi, suggesting that K. mikimotoi in this region was likely free of Amoebophridae infection.
