#Bacteria that end up inside of host cells for a long time (aka #endosymbionts) lose a lot of genes. In some cases these tiny #genomes can become unstable. One spectacular case of this is in cicadas. @noahspencer looked at what happens to #transcription of endosymbiont genes as their genomes erode and the dosage of genes becomes unbalanced. Here is a preprint showing what he found. Short version: these bacteria have almost completely lost control of their transcription!

Lucinid clams - #endosymbionts use environmental sulphide for #chemosynthesis. But some #symbiont proteins (sulphide-binding DsrC, metabolism-shunting GAPDH) are found in distant tissues, including haemolymph... how? @jillpeterplan #EESSymbiosis

Anaeramoeba (actually a metamonad) - @jon_hultqvist talks about the striking array of tightly apposed methanogenic #archaeal #endosymbionts and #hydrogenosomes - host has many Rab genes, perhaps for complex membrane management? #EESSymbiosis

#Chlamydiae is an ancient bacterial phylum infamous for the human pathogen #Chlamydia

All chlamydiae are #endosymbionts that infect hosts ranging from #protists to animals. Yet, they have drastically different genomes!

How did Chlamydiae #evolve and differences come about?

#Bacterial #endosymbionts often protect their hosts from threats. For instance, #Wolbachia inhibit #viral #pathogens in #insects and #Hamiltonella defensa protect from #parasitoid wasps.

Here, researchers report that #Regiella insecticola protects #aphids from Acyrthosiphon pisum virus. This is only the second #symbiont reported to inhibit viral pathogens in #arthropods.

RT @virtigation: #Bacterial #symbionts & #endosymbionts could serve as a novel #whitefly control method. A new study by our partner @LIST_Luxembourg has found that plant-mediated rifampicin treatment of #Bemisiatabaci whitefly disrupts, but does not eliminate endosymbionts https://www.nature.com/articles/s41598-022-24788-0#article-info

Hey there #ScienceMastodon
I am a Postdoc with Thijs Ettema at Wageningen University and Research (WUR) in the Netherlands.

I like to spend my time looking into the ancient evolution of prokaryotic genomes, mostly Chlamydiae and Asgard archaea.
