Bacteriocytes are host cells specialized to harbor symbionts in certain insect taxa. The
adaptation, development, and evolution of bacteriocytes underlie insect symbiosis …

Various animals are associated with specific endosymbiotic microorganisms that provide the
host with essential nutrients or confer protection against natural enemies. Genomic analyses …

For over 300 million years, insects have relied on symbiotic microbes for nutrition and
defence. However, it is unclear whether specific ecological conditions have repeatedly …

The smallest reported bacterial genome belongs to Tremblaya princeps, a symbiont of
Planococcus citri mealybugs (PCIT). Tremblaya PCIT not only has a 139 kb genome, but …

Stable endosymbiosis of a bacterium into a host cell promotes cellular and genomic
complexity. The mealybug Planococcus citri has two bacterial endosymbionts with an …

Many insect groups depend on ancient obligate symbioses with bacteria that undergo long‐
term genomic degradation due to inactivation and loss of ancestral genes. Sap‐feeding …

Symbiotic associations between bacteria and eukaryotes exhibit a range of transmission
strategies. The rates and distributions of transmission modes have not been thoroughly …

Abstract Mealybugs (Hemiptera: Pseudococcidae, Rhizoecidae and Xenococcidae) are
important organisms for understanding processes of evolution, especially microbial …

Palaeontologically, eubacteria are> 3× older than neomura (eukaryotes, archaebacteria).
Cell biology contrasts ancestral eubacterial murein peptidoglycan walls and derived …

Symbiotic associations play a pivotal role in multicellular life by facilitating acquisition of new
traits and expanding the ecological capabilities of organisms. In insects that are obligatorily …
