近年来全球气候变化趋势越加严峻，特别在南北极地区。本文以Polarellaglacialis－一种对高纬度南极海冰及北冰洋水层甲藻产量有重要贡献而其生理特性尚属空白的两极甲藻为代表，通过观察不同温度和光周期下P.glacialis的生长、细胞周期特征与Rubisco和类PCNA蛋白等的表达量变化以阐明该藻在极地极端光周期下的生长特性，回答以该藻为代表的极地藻类能否通过改变或调整表型特性来适应逐渐升高的环境温度。 对已成功分离培养的P.glacialis的两藻株CCMP2088、CCMP1383设置了不同的温度和光照周期：4°C和14L/10D光照周期、4°C和10L/14D光照周期、10°C. Polarella glacialis, an important dinoflagellate contributes substantially to the phytoflagellate biomass and primary production in the Antarctic sea ice and the Arctic Ocean. Few physiological characteristics of it have ever been studied. In this paper we are trying to understand how P. glacialis acclimates the polar days and polar nights, and if it can acclimate or adjust through phenotypic resp. 学位：理学博士 院系专业：海洋与环境学院海洋学系_海洋生物学 学号：22420060153347
