The paper identifies an Esx secretion system in Actinomycetota that defends against parasitic Patescibacteria by sensing epibionts and triggering a transcriptional response.

The paper shows that Pseudomonas bacteria use a single regulatory pathway to coordinate defense against both bacterial and viral threats across multiple species.

The paper identifies teichuronic acid oligosaccharides as the receptor for umbrella toxins and shows targeting specificity arises from lectin domain recognition of variable TUA-WTA structures.

This study shows that secretoneurin stimulates ovulation in zebrafish by increasing gene expression in the hypothalamic-pituitary-ovarian axis and inducing ovulation in anovulatory females.

This study identifies umbrella toxin particles produced by Streptomyces that inhibit the growth of competing bacterial species, distinct from small molecule antibiotics.
