摘要: 浮游植物具有复杂的生活史。与陆生植物的休眠细胞类似,孢囊是浮游植物生命过程中重要的一环,它在抵抗外界压力、应对不良环境、维持生理稳态、维护物种繁衍等方面具有重要意义。在一些生态事件中,更有人提出孢囊是藻类周期性暴发的种子库。然而,相比于成熟细胞,孢囊的生态生理学研究还相对缺乏。为了加深对孢囊生命过程和生态意义的认识,我们以近20年的文献为重点梳理了浮游植物孢囊研究的最新进展。概述了典型浮游植物甲藻、硅藻孢囊(休眠孢囊、游动孢囊、成熟孢囊)的类型及形成因素,总结了孢囊的形成机制、生理特征和萌发要素,并阐释了孢囊在藻类进化和海洋碳循环中的意义。本文旨在总结孢囊的适应性和可塑性,加深对藻类生存策略的生态学机制的认识。

Abstract: Phytoplankton have a complex life-cycle. Resting cysts are formed like terrestrial plants. Cysts play important roles in resisting environmental pressure, surviving adverse environment, maintaining physiological homeostasis, and maintaining species reproduction. In some ecological events, cysts were served as “seed bank” for periodical algal blooming. However, compared with the mature cells, the ecophysiological research on cysts is relatively limited. To deepen our understanding on life-cycle and ecological roles of cysts, we reviewed the researches on cysts in the past two decades. Firstly, we outlined the types (resting cysts, zoocysts, mature cysts) and factors that affected the formation of cysts of typical dinoflagellates and diatoms. Secondly, we summarized the formation mechanism, physiological characteristics and germination factors of cysts. Finally, we discussed the significance of cysts in algal evolution and in ocean carbon cycle. This review, summarizing the adaptability and plasticity of cysts, would shed light on ecological mechanism of algae survival strategy.
