Poison acidified crops sanitize food and limit disease transmission while at the same time structuring the gut microbiota and thus contribute to the ecological and evolutionary success of formicine ants.
Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.
This review serves as a gateway to experimental, conceptual, and quantitative themes of cytoplasmic incompatibility (CI) and outlines significant gaps in the understanding of CI's mechanism that are ripe for investigation.
Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.
Environmental transmission is atypical of symbionts that have undergone genome degradation, yet genetically reduced deep-sea anglerfish symbionts likely persist in the deep sea biome in search of a new host.
