摘要:

微生物在全球生态系统中占据着重要地位, 其中一个重要的研究领域是微生物与环境(包括无机环境与生物环境)之间的相互作用。在生态相互作用过程中, 微生物常常通过自组织形成特定的空间模式。微生物的空间模式在种群稳定性、群落动态变化以及维持合作行为方面具有重要作用。本文中, 我们梳理了当下对微生物空间自组织及其所形成的空间模式的研究内容, 首先介绍什么是空间自组织, 再根据生态相互作用类型对自组织的空间模式进行描述, 其中重点讨论合作与竞争中的空间模式, 接着关注微生物空间自组织的过程, 最后我们指出空间自组织对整个群体的结构和功能稳定具有重要意义。研究微生物种群间相互作用中的空间模式, 有助于探索维持合作行为的新机制, 进而为微生物共生系统的构建提供新的理解。

Abstract

Background & Aims: Microorganisms play a significant role in the global ecosystem, and the interaction of microorganisms with the environment (including inorganic environment and biotic environment) is one of the important topics in this research area. Microorganisms often form specific spatial structures or spatial patterns through self-organization. Spatial patterns of microorganisms were crucial for population stability, dynamics of community and maintenance of cooperative behavior, which have been well documented by theoretical and experimental studies over the past decades. Here we aim to summarize how ecological interactions facilitate self-organization and spatial pattern in microorganisms and demonstrate the effects of spatial patterns on microbial functions.

Progress: Firstly, we introduced the concept of spatial self-organization, followed by explaining spatial patterns of self-organization in different ecological interactions, especially in microbial cooperation and competition. Next, we focused on the process of microbial spatial self-organization, and finally emphasized that spatial self-organization was essential for the structural and functional stability of microbial community.

Prospects: Exploring spatial self-organization accompanying cooperative behavior in ecosystem may bring up new mechanisms for the maintenance of cooperative behavior, and provide new insights for the construction of microbial symbiotic systems.

Key words: microorganism, spatial pattern, spatial self-organization, microbial interaction, cooperation and competition
