Oral Actinobacteria sense and defend against parasitic epibionts
It is shown that Actinomycetota fend off Patescibacteria using the Esx secretion system and that this response occurs at the transcriptional level and is mediated by a previously undescribed threat sensing pathway whose activation leads to threonine phosphorylation of an FHA domain-containing output protein.
