AbstractSynechococcus, the main group of marine picophytoplankton, would change their structure composition, physiological characteristics and carbon-fixation capacity responded to marine environmental variations, which is always an important scientific issue to assess the primary productivity of ecosystems and maintain the stability of ecosystems. Photosynthetically active radiation (PAR), as one of the most important environmental factors affecting plant life activities, not only restricts the growth of marine phytoplankton, but also determines the geographical distribution of marine Synechococcus. The existing results show that different phylogenetic clades of Synechococcus occupy different ecological niches, and pigment types and abundance exhibit a PAR-dependent geographical distribution. Moreover, the light-controlled culture experiment confirms that PAR could affect the growth rate, light-catching pigment contents and the expression of key gene of photosynthesis of Synechococcus. In this study, the adaptive response and regulatory mechanism of Synechococcus to PAR were summarized. Additionally, the concerned problems for future research were put forward for further understanding of theoretical study of phytoplankton adaptation to PAR.
Other Abstract聚球藻(Synechococcus)是海洋微微型浮游植物的主要类群,其结构组成、生理特征和固碳能力会随着海洋 环境变化发生动态响应,是研究生态系统初级生产力和维持生态系统稳定性的重要课题。 光合有效辐射(PAR)作为 影响植物生命活动最重要的环境要素之一,既是海洋浮游植物生长的限制因子,也是海洋聚球藻地理分布的决定因 子。 已有研究表明:聚球藻不同发育分支占据不同的生态位,其色素类型和丰度的地理分布受 PAR 影响。 控光培养 实验也证实,PAR 差异能够影响聚球藻的生长速率、捕光色素含量及光合作用关键基因的表达量。 本文总结了聚球 藻对 PAR 的适应性响应与调控机制,并对未来研究领域应关注的问题进行了展望,以期为浮游植物适应 PAR 的理论 研究提供科学参考。
