Communication between microorganisms in aquatic environments can influence ecosystem function and determine the structure and composition of microbial populations. This microbial cross talk can be mediated by excretion of specialized metabolites or extracellular vesicles (EVs). Recently it has become apparent that cells across all domains of life produce EVs that may convey specific targeted signals that can modulate cell fate, morphology and susceptibility to viruses. The vast majority of knowledge about EVs is derived from studies of mammalian tissues, parasitic host-pathogen interactions and model bacterial systems. Very little is known about the role of EVs in aquatic environments, although they have potential to influence community structure and trophic-level interactions. We propose functions and ecological implications of communication via EVs in aquatic microbial ecosystems.
水生环境中微生物之间的交流可以影响生态系统功能，并决定微生物种群的结构和组成。这种微生物间的交流可以通过分泌专门的代谢物或细胞外囊泡（EVs）来介导。最近，人们已经清楚地认识到，所有生命领域的细胞都会产生 EVs，这些 EVs 可能传递特定的靶向信号，从而调节细胞命运、形态和对病毒的敏感性。关于 EVs 的绝大多数知识都是来自于对哺乳动物组织、寄生虫宿主-病原体相互作用和模式细菌系统的研究。虽然 EVs 有可能影响群落结构和营养级相互作用，但对于它们在水生环境中的作用知之甚少。我们提出了通过 EVs 在水生微生物生态系统中进行通讯的功能和生态影响。
