Bacteria inhabit all known ecological niches and establish interactions with organisms from all kingdoms of life. These interactions are mediated by a wide variety of mechanisms and very often involve the secretion of diverse molecules from the bacterial cells. The Type VI secretion system (T6SS) is a bacterial protein secretion system that uses a bacteriophage-like machinery to secrete a diverse array of effectors, usually translocating them directly into neighbouring cells. These effectors display toxic activity in the recipient cell, making the T6SS an effective weapon during inter-bacterial competition and interactions with eukaryotic cells. Over the last two decades, microbiology research has experienced a shift towards using systems-based approaches to study the interactions between diverse organisms and their communities in an ecological context. Here, we focus on this aspect of the T6SS. We consider how our perspective of the T6SS has developed and examine what is currently known about the impact that bacteria deploying the T6SS can have in diverse environments, including niches associated with plants, insects and mammals. We consider how T6SS-mediated interactions can affect host organisms by shaping their microbiota, as well as the diverse interactions that can be established between different microorganisms through the deployment of this versatile secretion system.

细菌武器的生态影响:微生物相互作用和 VI 型分泌系统

细菌栖息在所有已知的生态位中,并与来自所有生命王国的生物建立相互作用。这些相互作用由多种机制介导,并且通常涉及从细菌细胞中分泌不同的分子。VI 型分泌系统 (T6SS) 是一种细菌蛋白质分泌系统,它使用类似噬菌体的机制来分泌多种效应物,通常将它们直接转移到邻近细胞中。这些效应器在受体细胞中显示出毒性活性,使 T6SS 在细菌间竞争和与真核细胞相互作用期间成为有效武器。在过去的二十年里,微生物学研究已经转向使用基于系统的方法来研究生态环境中不同生物及其群落之间的相互作用。在这里,我们专注于 T6SS 的这一方面。我们考虑了我们对 T6SS 的看法是如何发展的,并研究了目前已知的关于部署 T6SS 的细菌在不同环境中可能产生的影响,包括与植物、昆虫和哺乳动物相关的生态位。我们考虑了 T6SS 介导的相互作用如何通过塑造微生物群来影响宿主生物,以及通过部署这种多功能分泌系统可以在不同微生物之间建立的各种相互作用。我们考虑了我们对 T6SS 的看法是如何发展的,并研究了目前已知的关于部署 T6SS 的细菌在不同环境中可能产生的影响,包括与植物、昆虫和哺乳动物相关的生态位。我们考虑了 T6SS 介导的相互作用如何通过塑造微生物群来影响宿主生物,以及通过部署这种多功能分泌系统可以在不同微生物之间建立的各种相互作用。我们考虑了我们对 T6SS 的看法是如何发展的,并研究了目前已知的关于部署 T6SS 的细菌在不同环境中可能产生的影响,包括与植物、昆虫和哺乳动物相关的生态位。我们考虑了 T6SS 介导的相互作用如何通过塑造微生物群来影响宿主生物,以及通过部署这种多功能分泌系统可以在不同微生物之间建立的各种相互作用。
