摘要

趋化作用使微生物能够在化学刺激下指挥运动。细菌利用这种行为与动植物甚至更大的微生物建立空间联系。然而,目前的理论认为,受趋化感觉系统的限制,细菌无法感知来自小于几微米的细胞的化学梯度,因此趋化作用无法用于单个细菌之间的相互作用。然而,最近的证据显示,细菌趋化的精确性达到了令人惊讶的水平,而且趋化在细菌细胞之间的代谢物交换中也发挥了作用。如果细菌间的趋化感应确实普遍存在,那么它可能代表了细菌间相互作用中一种重要的、但在很大程度上被忽视的表型,并在形成合作与竞争关系方面发挥重要作用。

Swimming towards each other: the role of chemotaxis in bacterial interactions.

Chemotaxis allows microorganisms to direct movement in response to chemical stimuli. Bacteria use this behaviour to develop spatial associations with animals and plants, and even larger microbes. However, current theory suggests that constraints imposed by the limits of chemotactic sensory systems will prevent sensing of chemical gradients emanating from cells smaller than a few micrometres, precluding the utility of chemotaxis in interactions between individual bacteria. Yet, recent evidence has revealed surprising levels of bacterial chemotactic precision, as well as a role for chemotaxis in metabolite exchange between bacterial cells. If indeed widespread, chemotactic sensing between bacteria could represent an important, but largely overlooked, phenotype within interbacterial interactions, and play a significant role in shaping cooperative and competitive relationships.

期刊介绍: Trends in Microbiology serves as a comprehensive, multidisciplinary forum for discussing various aspects of microbiology, spanning cell biology, immunology, genetics, evolution, virology, bacteriology, protozoology, and mycology. In the rapidly evolving field of microbiology, technological advancements, especially in genome sequencing, impact prokaryote biology from pathogens to extremophiles, influencing developments in drugs, vaccines, and industrial enzyme research.
