磷(P)是所有生物必不可少的结构和功能成分，被认为是海洋生态系统中最终的限制性营养物质。为了优化其获取，原生动物、海绵、有孔虫、蛤蜊和珊瑚礁珊瑚等海洋物种与藻类建立了共生关系，藻类回收动物宿主的废物，并将溶解的无机营养物质转化为有机分子，使其成为宿主的生物可利用物。这种联系在环境养分可利用性低的环境中提供了竞争优势。本文综述了与藻类共生的珊瑚礁生物磷源的研究现状，讨论了共生生物吸收和储存磷的途径，并对富营养化诱导的磷富集对藻类和寄主生理的影响进行了评价。最后，我们给出了知识空白的概述和开放的问题，应该解决，以更好地了解磷在珊瑚礁共生功能中的作用。
Phosphorus (P), an essential structural and functional component of all living organisms, is considered to be the ultimate limiting nutrient in marine ecosystems. To optimize its acquisition, marine species such as protozoa, sponges, foraminifera, clams, and reef corals, among others, have entered symbiotic relationships with algae, which recycle waste products of the animal host and transform dissolved inorganic nutrients into organic molecules, making them bioavailable to their host. Such associations provide a competitive edge in an environment where ambient nutrient availability is low. The aim of this review is to summarize the current knowledge on the P sources available to reef organisms with algal symbionts, to discuss the means by which P is taken up and stored within the symbiosis, and to assess the effects of eutrophication-induced phosphate enrichment on the algal and host physiology. Finally, we give an overview of knowledge gaps and open questions that should be addressed to better understand the role of phosphorus in reef symbioses functioning.
