It was originally hypothesized that only dinoflagellates could produce harmful algal toxins, but a deadly bloom of Pseudo-nitzschia occurred in 1987 in the bays of Prince Edward Island, Canada, and lead to an outbreak of ASP. Blooms have since been characterized in coastal waters worldwide and have been linked to increasing marine nutrient concentrations. == Morphology and Physiology == Pseudo-nitzschia are bilaterally symmetrical pennate diatoms. Cell walls are made up of elongated silica frustules and contain a central raphe, which secretes mucilage that allows the cells to move by gliding. Cells are often found in overlapped, stepped colonies and exhibit collective motility.〔 Species reproduction is often asexual and results in the size reduction of cells. They then undergo sexual reproduction to revert to their original size. Pseudo-nitzschia are autotrophic organisms meaning they synthesize their own food through the use of light and nutrients in photosynthesis. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pseudo-nitzschia」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
