For instance, the lytic phage ϕ29 became a model for studying processes such as viral DNA packaging, replication, and transcription. By contrast, only a handful of temperate B. subtilis phages have been comprehensively characterized. However, the discovery of a peptide-based quorum sensing (QS) system in 2017 has brought temperate B. subtilis phages, particularly those of the SPβ family, back into the focus of research. The QS system is used by these phages to modulate lysis-lysogeny decisions. Meanwhile, many key components of the lysis-lysogeny management system have been identified. It turned out that a complex co-adaptation between the B. subtilis host cell and SPβ-like phages occurred during evolution and that a host-encoded toxin-antitoxin system plays a key role in controlling lysis-lysogeny decisions. There are many similarities and many important differences between the two well-studied model phages. Thus, a further comparative analysis of the lysis-lysogeny systems is essential to uncover the fundamental differences between ϕ3T and SPβ. Moreover, we believe that it would be exciting to revive research on temperate B. subtilis phages that are not related to SPβ-family phages.</p>","PeriodicalId":23275,"journal":{"name":"Trends in Microbiology","volume":" ","pages":"387-396"},"PeriodicalIF":14.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142792583","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}

In recent years, exciting new bioinformatic tools, many of which are based on machine learning, facilitate the challenging task of gene and protein function discovery in the era of big genomics data, leading to the generation of testable hypotheses for bacterial protein functions. The new tools allow prediction of protein structures and interactions and allow sensitive and efficient sequence- and structure-based searching and clustering.

We highlight the versatile role of aerobic methane-oxidizing bacteria in electrochemically driven methane oxidation, and the non-syntrophic lifestyle of anaerobic methanotrophic archaea (ANME) enabled by their extracellular electron transfer (EET) pathways. These aspects are followed by a review of recent findings on the potential reversibility of methanogen metabolism, with a focus on the proposed EET pathways that may facilitate their shift to a methane-oxidizing phenotype, a topic that remains under active investigation and debate.
