@genomebiolevol.bsky.socialPau, @syngnathid.bsky.social et al. find that chromosome-wide dosage compensation can be maintained by global regulatory mechanisms that persist through sex chromosome turnover, even when gene-by-gene constraints are weak.
@genomebiolevol.bsky.socialThis month's GBE Author Spotlight focuses on Kanako Koyanagi of Hokkaido University, first author of this month's article on the evolution of wild rice species.
@genomebiolevol.bsky.social@guyleonard.eurosky.social @brockhurstlab.bsky.social et al. report a T2T genome for Micractinium conductrix, an endosymbiont of Paramecium bursaria, publishing one of the most complete Chlorellaceae algal genome assemblies to date
@molbioevol.bsky.socialMรผller et al. show that in hybrid-origin, parthenogenetic whiptail lizards, mutations accumulate in genes involved in core cellular functions, supporting predictions of mutation accumulation in asexual lineages.

@genomebiolevol.bsky.socialThe September GBE Highlight features the article by Koyanagi, Kotoku & Kishima on the role of genetic exchange in the evolution of wild rice.
Highlight: Ghosts of Long-Lost Connections in the Genomes of Wild Rice

@genomebiolevol.bsky.socialKanako Koyanagi, Yuta Kotoku & Yuji Kishima find evidence of ancient introgression between currently geographically separated and evolutionarily divergent Oryza lineages, leaving detectable footprints across their modern genomes
@molbioevol.bsky.socialรlvarez-Carretero et al. reexamine claims that molecular clocks are uninformative for dating animal and placental mammal origins, vindicating deep molecular divergence estimates over literalist fossil-based ones.

@genomebiolevol.bsky.social@fanny-pouyet.bsky.social et al. benchmarked three tree sequence reconstruction methods software by comparing the imbalance of reconstructed trees by these methods with that of the true simulated trees.
@molbioevol.bsky.socialKoch et al. offer insights into the evolution of complex gene repertoires in venoms of predatory cone snails, uncovering how neuropeptide genes were recruited >20 times into the venom and neofunctionalized as doppelgรคnger toxins.
@molbioevol.bsky.socialS. Kumar, K. Tamura & S. Sharma present a phylogenomic subsampling-upsampling framework (PSU) that cuts runtime/memory by orders of magnitude while preserving accuracy in bootstrap support, model selection, and divergence time estimates.
@genomebiolevol.bsky.socialLindahl et al. find that amino acid synthesis capacity (prototrophy) in E. coli is maintained over evolutionary timescales by horizontal gene transfers, restoring functions lost by accumulation of detrimental mutations.
@genomebiolevol.bsky.socialKrasiฤผลikova assembled a T2T genome of Trypanosoma congolense, comparing it with T. brucei to reveal shared and divergent architecture, and provided preliminary evidence for differing strategies for antigenic variation via a common antigen
@molbioevol.bsky.socialBodin, Morlon & @bperezlamarque.bsky.social reevaluated evidence for codiversification in mycorrhizal symbioses, finding that closely related plants often interact with closely related fungi, but their phylogenies do not match.
@molbioevol.bsky.social@marzena-marszalek.bsky.social et al. integrate WGS and RNAseq from 282 wild yeast strains, finding robust signals of nonsense-mediated mRNA decay but no clear evidence of transcriptional adaptation.
@genomebiolevol.bsky.socialEvseeva et al. sequenced a historic plant pathogen outbreak that swept across the island of Martinique, highlighting the role of horizontal transfer in shaping the ecological success of the emerging pathogen Ralstonia spp.
@molbioevol.bsky.socialYฤฑldฤฑrฤฑm and James inferred gene-level selective constraints across the genomes of mice, fruit flies, and yeast, finding that gene-level complexity provides a more informative definition of complexity for DFE variation than organism-level labels.
@molbioevol.bsky.socialLetcher et al. reveal how Mesorhabditis nematodes evolved a new Y chromosome from sexual ancestors in species that transitioned into autopseudogamy - females produce clonal females plus rare males that are needed for fertilization.
