Diatoms represent one of the most successful groups of marine phytoplankton and are major contributors to ocean biogeochemical cycling. They have colonized marine, freshwater and ice environments and inhabit all regions of the World's oceans, from poles to tropics. Their success is underpinned by a remarkable ability to regulate their growth and metabolism during nutrient limitation and to respond rapidly when nutrients are available. This requires precise regulation of membrane transport and nutrient acquisition mechanisms, integration of nutrient sensing mechanisms and coordination of different transport pathways. This review outlines transport mechanisms involved in acquisition of key nutrients (N, C, P, Si, Fe) by marine diatoms, illustrating their complexity, sophistication and multiple levels of control.
硅藻是海洋浮游植物中最成功的群体之一，是海洋生物地球化学循环的主要贡献者。它们已经在海洋、淡水和冰环境中殖民，并栖息在世界海洋的所有地区，从极地到热带。它们的成功得益于在营养限制时调节生长和新陈代谢的非凡能力，以及在有营养物质时快速响应的能力。这需要对膜转运和养分获取机制进行精确调节，整合养分感应机制，并协调不同的运输途径。本综述概述了海洋硅藻获取关键养分（N、C、P、Si、Fe）的运输机制，说明了它们的复杂性、复杂性和多层次的控制。
