#endosymbionts — Public Fediverse posts

🦠 New #symbionts in #wastewater: #denitrifying #protist #endosymbionts are found in #sewage plants all over the world. One common species releases #nitrousoxide.

What happens to endosymbionts and their hosts as they forego sovereignty? Athreya et al. find new reasons why an evolutionary transition might not happen, and that host-symbiont mutual dependence might evolve faster than reproductive cohesion.

Scientists discover more #mitochondria-like #symbionts with surprising metabolic capacities https://phys.org/news/2024-12-scientists-mitochondria-symbionts-metabolic-capacities.html

Genetic potential for aerobic respiration and #denitrification in globally distributed respiratory #endosymbionts https://www.nature.com/articles/s41467-024-54047-x

"They found a unique #bacterium that lives inside a ciliate (#protists) and provides it with energy... reminiscent of #mitochondria, with the key difference that the #endosymbiont derives energy from the respiration of nitrate, not oxygen."

This is an unexpected result.

Although Camponotus ants require the nutritional services of the endosymbiotic bacteria Blochmannia to rear larvae to adulthood, a new study finds that the bacteria itself is harmful to the adult ants.

Transcription activator-like effector protects bacterial #endosymbionts from entrapment within fungal hyphae: Ingrid Richter et al. https://www.cell.com/current-biology/fulltext/S0960-9822(23)00623-1

"the #bacterial species #Mycetohabitans rhizoxinica lives happily in the #hyphae of the #fungus #Rhizopus microsporus only when the #bacteria produce a certain protein."

#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!

#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?

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.
