The paper studies the evolution of insect-Escherichia coli mutualism by analyzing transcriptional changes in bacterial lineages that improve host performance.

This study shows that engineered Escherichia coli strains can outcompete native Pantoea symbionts in stinkbugs but provide less host fitness benefits, revealing a conflict between colonization success and mutualism.

This study evolves a minimal genome bacterium to grow at a lower temperature, revealing genetic and non-genetic adaptation mechanisms.

The paper shows that disrupting the tryptophanase gene in bacteria enables mutualism with stinkbugs, suggesting this gene loss facilitated the evolution of insect-bacterium mutualism.

The paper investigates the migration of bacteriocytes into cockroach ovaries during postembryonic development, revealing how symbiont transmission occurs through nymphal stages and inter-oocyte movement.

This study identifies uric acid accumulation in cockroach wings, showing it is present in multiple species and reversibly affected by feeding and starvation.

The paper identifies a novel defensive fungal symbiosis in stinkbugs where females transfer fungi to eggs to protect them from wasp parasitism.

This study identifies (TTGGG)n as the telomeric repeat in Odonata, showing its ancestral acquisition and repeated divergence across species.

The paper investigates host specificity in symbiotic bacteria by testing artificial and natural E. coli strains in stinkbug species, finding that artificial strains show strict host specificity while natural strains have broader host ranges.

This study investigates the effect of high temperature on symbiont suppression in the stinkbug Plautia stali, finding that 37°C treatment effectively reduces symbiont titers with minimal host damage.

This study identifies a novel monocarboxylate transporter, 3OHKT, responsible for 3-hydroxykynurenine uptake in ommochrome pigmentation in silkworms and butterflies.
