This study shows soil pH filters symbiotic bacteria before they colonize insect guts, affecting stink bug growth and reproduction.

This study shows how bacteria use flagellar wrapping to move through narrow passages, with hook flexibility being essential for this movement.

This study shows that horizontal gene transfer of nicotine catabolism genes in Arthrobacter enables its colonization of tobacco roots, shaping the root microbiota community.

This study investigates how Caballeronia symbionts outcompete other bacteria in the gut of Riptortus pedestris by evolving traits like chemotaxis and resistance to antimicrobial peptides.

This study shows that wild gut microbiomes suppress Aeromonas in medaka under domesticated conditions, preventing pathogen colonization through habitat-derived microbial interactions.

The paper identifies hundreds of antimicrobial peptides in the insect gut that create a selective barrier for symbionts, with resistance mechanisms crucial for colonization.

This study uses transposon sequencing to identify essential genes and gut-specific nutrients in the insect symbiont Caballeronia insecticola.
