#prokaryotic — Public Fediverse posts

The #mitochondrion represents a #biological singularity, a discrete #evolutionary event that fundamentally partitioned life on #Earth into two distinct energetic stratums: the #prokaryotic and the #eukaryotic. While colloquially reduced to the moniker of "cellular powerhouse," the mitochondrion is, in functional reality, a highly integrated endosymbiont that serves as the master regulator of eukaryotic physiology

Extreme environments are coded into the #genomes of the organisms that live there https://theconversation.com/extreme-environments-are-coded-into-the-genomes-of-the-organisms-that-live-there-219072

Environment and #taxonomy shape the genomic signature of #prokaryotic extremophiles https://www.nature.com/articles/s41598-023-42518-y

"The expectation was that all the clusters would be along taxonomic lines: #bacteria grouped with bacteria, and #archaea grouped with archaea. To our great surprise, this was not always the case... The only obvious commonality was that they were heat-loving #extremophiles."

"We propose that at least part of the #pangenome can be understood as a set of #genes with relationships that govern their likely cohabitants, analogous to an ecosystem’s set of interacting organisms. Our findings indicate that intragenomic gene fitness effects may be key drivers of #prokaryotic #evolution, influencing the repeated emergence of complex gene–gene relationships across the pangenome."

These #bacterial #biochemistry homologs, which are annotated as S41 peptidases, are single-domain proteins with sequence and structural similarity to each of the four human IRBP domains https://www.pnas.org/doi/10.1073/pnas.2214815120

When can syntrophic microbial cooperation win over selfish cheaters? https://ecoevocommunity.nature.com/posts/when-can-syntrophic-microbial-cooperation-win-over-selfish-cheaters

Eco-evolutionary modelling of microbial #syntrophy indicates the robustness of cross-feeding over cross-facilitation https://www.nature.com/articles/s41598-023-27421-w

Most #prokaryotes rely on syntrophic partners, but they rarely evolve to full #endosymbiosis. If #mitochondria have originated from a syntrophic #symbiosis, a burning question arises: Why aren't there more #prokaryotic syntrophies that turn into endosymbiosis?

#Microbe filter feeders

This recent research explores how mesh feeding #zooplankton are able to feed directly on #prokaryotic #microorganiisms and suggests #Prochlorococcus (#Cyanobacteria) may be able to evade #predation.
