Hägglund et al. employed sequence-based and structure-based search methods to investigate the origin of the anammoxosome, the only known energy-producing organelle in bacteria, and its key enzyme, the hydrazine synthase complex.
Background Control and elimination of schistosomiasis is an arduous task, with current strategies proving inadequate to break transmission.bioRxiv

#ExtremeEnvironments offer an unprecedented opportunity to understand #microbial #eukaryotic #ecology, #evolution, and #genome #biology: Hannah Rappaport & Angela Oliverio nature.com/articles/s41467-023…
“several lineages of #amoebae were often recovered from extremely high temperature environments. Studying those lineages may yield great insight into how eukaryotic cells can adapt to life in extremely hot environments.”
Researchers are investigating microbial eukaryotic life in extreme environments, like Lassen National Park's geothermal lake.Dan Bernardi-Syracuse (Futurity)

Are prophages good or bad for bacteria? The data shows they provide heaps of benefits

Phages dominate every ecosystem on the planet. While virulent phages sculpt the microbiome by killing their bacterial hosts, temperate phages provide unique growth advantages to their hosts through lysogenic conversion.bioRxiv

Fascinating study on #genome #evolution :
Scaling of Protein Function Across the Tree of Life
"The abundance of functional categories in a given genome scales with genome size, suggesting that universal constraints shape category abundance. Here we look across the tree of life to understand how genome evolution may be related to functional scaling. "

Scaling laws are a powerful way to compare genomes because they put all organisms onto a single curve and reveal non-trivial generalities as genomes change in size.bioRxiv

The parasite #Trypanosoma brucei lives and replicates in insect vectors like the fly. During the mating process, both its #nucleus and #mitochondrion replicate and exchange their genetic information, while the mitochondrial mechanism is still incompletely understood.
