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

Vertical and horizontal transmission are terms that describe the transfer of symbionts from
parents to offspring and among unrelated hosts, respectively. Many symbionts, including …

Bacterial intracellular symbiosis (endosymbiosis) is widespread in nature and impacts many
biological processes. In holometabolous symbiotic insects, metamorphosis entails a …

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

Gastrotricha and Platyhelminthes form a clade called Rouphozoa. Representatives of both
taxa are main components of meiofaunal communities, but their role in the trophic ecology of …

In many animal hosts, microbial symbionts are housed within specialized structures known
as symbiotic organs, but the evolutionary origins of these structures have rarely been …

The remarkable regenerative abilities of flatworms are closely linked to neoblasts–adult
pluripotent stem cells that are the only division-competent cell type outside of the …

Corals are the main primary producers of coral reefs and build the three-dimensional reef
structure that provides habitat to more than 25% of all marine eukaryotes. They harbor a …

Hosts of chemoautotrophic bacteria typically have much higher biomass than their
symbionts and consume symbiont cells for nutrition. In contrast to this, chemoautotrophic …

The ontogenetic origins of the bacteriocytes, which are cells that harbour bacterial
intracellular endosymbionts in multicellular animals, are unknown. During embryonic …
