Antimicrobial peptides (AMPs) are short, mainly positively charged, amphipathic molecules. AMPs important effectors of the immune response in insects with a broad spectrum antibacterial, antifungal, and antiparasitic activity. In addition to these well-known roles, exhibit many other, often unobvious, functions host. They support elimination viral infections. participate regulation brain-controlled processes, e.g., sleep non-associative learning. By influencing neuronal health, communication, activity, they can affect functioning insect nervous system. Expansion AMP repertoire loss their specificity is connected aging process lifespan insects. Moreover, take part maintaining gut homeostasis, regulating number endosymbionts as well reducing foreign microbiota. turn, presence venom prevents spread infection social insects, where prey may be source pathogens.

The bean bug Riptortus pedestris obtains a specific bacterial symbiont, Caballeronia insecticola ( Burkholderia ), from the environmental soil and harbors it in posterior midgut region that is composed of hundreds crypts. While newly hatched aposymbiotic insects possess primordial crypts with little or no lumen, colonization C. triggers swift development symbiotic organ, forming enlarged opened crypts, symbiont subsequently fills luminal cavities those mature cellular processes crypt triggered by are poorly understood. Here we identified fundamental mechanism symbiont-mediated investigating cell cycles intestinal epithelial cells. Intestinal stem cells located proliferate at base. Differentiated enterocytes migrate upward along layer as develops, induction apoptosis primarily occurred on tip side apoptotic then eventually were shed into hemolymph. proliferation rate base was low while high observed insects, resulting undeveloped short On contrary, gut-colonizing promoted simultaneously inhibited net growth generation lumen becomes colonized symbiont. These results demonstrated induces via finely regulating enterocyte cycles, enabling to stably abundantly colonize generated spacious host.

Gram-negative, aerobic, rod-shaped, non-spore-forming, motile bacteria, designated strains F2 T and PGU16, were isolated from the midgut crypts of bordered plant bug Physopelta gutta , collected in Okinawa prefecture, Japan. Although these derived different host individuals at times, their 16S rRNA gene sequences identical showed highest similarity to Paraburkholderia caribensis MWAP64 (99.3 %). The genome strain consisted two chromosomes plasmids, its size G+C content 9.28 Mb 62.4 mol% respectively; on other hand, that PGU16 three 9.47 mol%, respectively.
