Genome degradation results in nested symbiosis and endosymbiont replacement in cicadas - Nature Communications The evolutionary mechanisms leading to symbiont replacement in insects are not well understood. Zhou et al. show that genome degradation results in nested symbiosis and endosymbiont replacement in cic...

This is a really cool study on one of my favourite obligate symbiotic systems: Aphid + Buchnera by @jerrymaeda.bsky.social, @nancy-moran.bsky.social, & co.

Maternal symbiont transmission via envenomation in the parasitoid wasp Spalangia cameroni Intracellular symbionts of insects are typically transmitted transovarially. Weiss et al. find that in a nascent symbiosis between a Sodalis bacterium and a parasitoid wasp, Sodalis is injected with w...

Wolbachia Turns 100: The Journey of a Triumphant Endosymbiont In a century, Wolbachia has gone from a master reproductive manipulator to a partner in the fight against pathogens, exemplifying how a microbe can shape hosts and diseases.

Amazing work by @annamichalik.bsky.social and co., from the Jagiellonian University, showing a quite interesting "trick" from an #endosymbiont to insure its maternal transmission. As a puls, an "unstable" #Sulcia genome and a tiny #Vidania
