The genome and transcriptome of the snail Biomphalaria sudanica s.l.: Immune gene diversification and highly polymorphic genomic regions in an important African vector of Schistosoma mansoni
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 https://www.nature.com/articles/s41467-023-40657-4
“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.”

The Promise and Pitfalls of Prophages
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

Assessing species coverage and assembly quality of rapidly accumulating sequenced genomes
AbstractBackground. Ambitious initiatives to coordinate genome sequencing of Earth's biodiversity mean that the accumulation of genomic data is growing rapidly.Feron, Romain (Oxford University Press)
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 of Protein Function Across the Tree of Life
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
Mitochondrial #genome maintenance—the #kinetoplast story: Simona Amodeo et al. https://academic.oup.com/femsre/advance-article/doi/10.1093/femsre/fuac047/6855247
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.
