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.
The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
Morphological and fitness defects imposed on amoebae hosts by Burkholderia symbionts demonstrates symbiont species-specific effects and provides evidence of host adaptation to naturally acquired symbionts.
Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.
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.
