【 摘 要 】

ABSTRACT Despite the availability of massive microbial community data sets (e.g., metagenomes), there is still a lack of knowledge on what molecular mechanisms facilitate cross talk between microbes and prophage within a community context. A study published in mSphere by Jain and colleagues (M. Jain, L. A. Fleites, and D. W. Gabriel, mSphere 2:e00171-17, 2017, https://doi.org/10.1128/mSphereDirect.00171-17 ) reports on an intriguing new twist of how a prophage of the bacterium “Candidatus Liberibacter asiaticus” may have its lytic cycle suppressed partly because of a protein that is expressed by a cooccurring bacterium, Wolbachia. Both of these microbes coexist along with other microbial tenants inside their sap-feeding insect host, a psyllid. Although these results are still preliminary and alternative hypotheses need to be tested, these results suggest an interesting new dimension on how regulation of microbial genomes occurs in a community context.
