    塔玛亚历山大藻(Alexandriumtamarense)是一种广泛分布的有毒赤潮生物,不仅能形成大规模的赤潮,还可合成和生产麻痹性毒素,严重威胁到海洋生态系统的稳定、海洋生物资源的可持续发展和人类健康及生命财产安全。 本文以A.tamarenseCI01为研究对象,研究不同形态、不同浓度氮营养盐对细胞生长和毒素生产的影响;并运用蛋白质组学技术,比较研究了不同氮处理条件和不同生长期A.tamarenseCI01细胞蛋白质组的差异表达,确认和鉴定了一批差异表达蛋白,并探讨这些蛋白在A.tamarense响应高氨毒性中的作用及其在麻痹性毒素合成过程中的作用。主要研究结果如下: 1.两种氮源(硝...Alexandrium tamarense is a widespread dinoflagellate species which not only produces paralytic shellfish toxins which results in paralytic shellfish poisoning (PSP), but also causes harmful algal blooms (HABs). A. tamarense causing-HABs have become a worldwide conern due to its adverse effects and threaten to marine ecosystem, marine organisms, mariculture and human beings. This study used A. tam...学位:理学硕士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:2262007115235
