Understanding the underlying evolutionary and adaptive forces driving their production remains a fundamental question in biology.

It is thus assumed that these compounds are deployed by soil- or rhizosphere-dwelling bacteria as microbial weapons in competitive natural environments. Here, we challenge this reductionist perspective and present evidence that Bacillus CLPs are prominent chemical mediators of ecological interactions. They help Bacillus to communicate, compete, defend against predators, or cooperate and establish mutualistic relationships with other (micro)organisms. Additional parallel examples are highlighted in other genera, such as Pseudomonas. This broader perspective underscores the need for further investigation into the role of CLPs in shaping the adaptive strategies of key rhizobacterial species.</p>","PeriodicalId":23275,"journal":{"name":"Trends in Microbiology","volume":" ","pages":"80-95"},"PeriodicalIF":14.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142112338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
