The last chapter of my PhD work is now live on MBE. This has been an incredible project, combining genomics, proteomics, as well as transcriptomics that resolves total mRNA from ribosome-associated mRNA (which we infer to be in the process of translation).

@ironark.bsky.social et al. measured transcript abundance, ribosome-associated RNA, and protein abundance in bacterial endosymbionts, suggesting a mechanism for aberrant pseudogene-derived protein removal. 🔗 doi.org/10.1093/molbev/msag153 #societyjournal #evobio #molbio

We (@rileyshultz.bsky.social) tracked a recessive mutation from birth to death in honey bees. It causes ivory eyes. We collaborated across the continent to identify the mutation and it's downstream effects. Ultimately it is purified through selection on drones. We think Hamilton would be pleased!

Shultz @beeharpur.bsky.social et al. documented the trajectory of a spontaneous deleterious mutation from its origin in a single queen to its extinction, directly observing how haplodiploidy exposes recessive alleles to immediate purifying selection 🔗 doi.org/10.1093/molbev/msag156 #societyjournal

Chen, Qu & Zhang perform kingdom-wide evolutionary analyses across 364 Archaeplastida genomes and find massive PPR gene expansions in early-diverging land plants, predominantly driven by dispersed duplication associated with retroposition. 🔗 doi.org/10.1093/molbev/msag168 #societyjournal #PlantSky

Kayhani et al. find that introgression of warm-adapted alleles was largely successful despite the risk of introducing mitonuclear incompatibilities that could result from genome-wide shifts toward the paternal allele in Tigriopus californicus. 🔗 doi.org/10.1093/molbev/msag158 #societyjournal

Introgression of thermal tolerance alleles drives adaptation despite risk of mitonuclear conflict

Abstract. Hybridization may offer a form of genetic rescue from warming temperatures through the introgression of heat-adapted alleles from a high-toleranc

@prateekverma.bsky.social Albari & Marshall evaluate the potential of Y-linked genome editors to suppress or eliminate a mouse population on a small, isolated island - results suggest YLEs as a promising, ecologically manageable biocontrol tool 🔗 doi.org/10.1093/molbev/msag165 #societyjournal

Y-linked editors for invasive rodent control

Abstract. Invasive rodents are major contributors to biodiversity loss, particularly on islands where native species have evolved in their absence. Genetic

Zhu, Zhuo & Zhen show that natural selection has shaped the evolution of CTCF binding sites in primates, driving both conservation and innovation in chromatin organization and contributing to human-specific regulatory evolution. 🔗 doi.org/10.1093/molbev/msag167 #societyjournal #evobio

Evolution of CTCF binding sites in the human genome

Abstract. The CCCTC-binding factor (CTCF) is a master regulator of topologically associating domains (TADs), which shape 3D genome architecture and gene re

Weaver & Lowe suggest that placing regulatory elements in new genomic contexts primes them for neofunctionalization, and that regulatory rewiring after segmental duplication is a common mechanism underlying gene regulatory change. 🔗 doi.org/10.1093/molbev/msag140 #societyjournal #evobio #molbio

Segmentally Duplicated Regulatory Elements Undergo Human-Specific Rewiring

Abstract. Gene regulatory innovation underlies many phenotypic transitions. Transposable elements are an established mechanism for creating families of cis
