The paper examines host selectivity and adaptive strain enrichment in legume-rhizobia symbiosis, finding host genetic variation affects strain selectivity and nodule morphology correlates with mutualism dynamics.

This study shows male and female recombination rates in house mice evolve under distinct evolutionary programs, with males showing a unique adaptive optimum in their lineage.

The paper identifies intron-generating transposons in viral elements, suggesting dsDNA viruses may facilitate horizontal transfer of introners between species.

This study analyzes repetitive DNAs in eleven Hydnoraceae genomes, revealing distinct repeat profiles between genera and suggesting their role in genome evolution.

This study investigates how environmental stress affects developmental stability and canalization in rice, finding that drought reduces canalization and identifies specific genes involved.

This study shows that GC-biased gene conversion (gBGC) evolves under weak stabilising selection and can increase population load, suggesting it may have been positively selected in humans.

This study investigates how peptides interact with mineral surfaces and lipid vesicles, showing acidic residues bind minerals and arginine enhances phosphate mobilization, while different amino acid alphabets affect vesicle stability.

This study investigates within- and transgenerational plasticity in Physa acuta by analyzing gene expression changes in response to predator cues across two generations.

The paper shows that paralog interference enhances negative selection on loss-of-function mutations, preserving genetic redundancy over longer timescales.

The paper examines opsin gene evolution in Morpho butterflies, finding positive selection and co-evolving amino acids linked to light environment and wing coloration.

The paper analyzes the genomes of Asiatic mouflons in Iran to explore their role in sheep domestication and genetic introgression into domestic sheep populations.

The paper uses computer modeling of RNA-based protocells to explore how membrane-takeover could have driven early evolutionary processes by promoting phospholipid synthesis and related functional RNA species.

The paper estimates de novo mutation rates in three-spined sticklebacks using family trios and finds a mutation rate of 5.05 x 10^-9/bp/gen with a positive correlation between mutation rate and recombination rate.

The paper analyzes 1,375 Malawi cichlid genomes to show that sex-linked chromosomal inversions drive adaptive speciation through introgression and selection on neuro-sensory, physiological, and reproductive genes.

This study characterizes the CRY1 R263Q mutation in subterranean animals, showing altered circadian rhythms and gene expression in mice, but no major metabolic defects.

This study investigates Uloboridae spiders' venom loss and toxicity, finding they lack venom glands but retain toxin-like genes in digestive fluids with different toxic mechanisms.

This study examines antennal sensilla diversity in diurnal and nocturnal fireflies, finding that chemoreceptor counts and densities differ between sexes and activity patterns, while mechanoreceptors are conserved.

The paper examines how temperature and pH affect sequence diversity in microbial compartments across metagenomes from hydrothermal springs, finding pH has a stronger impact than temperature.

The paper identifies new divergent protein groups in ancient gene families from marine metagenomes, highlighting environmental diversity and potential biological novelty.

This study quantifies the contribution of gene gain and loss versus genome rearrangements to gene order evolution in bacteria and archaea, finding gene gain and loss dominate.
