#evolbio — Public Fediverse posts

Moreno et al. applied experimental evolution to identify genes conferring host specificity to L. pneumophila, highlighting the importance of mutations targeting the LerC protein and the LPS synthesis cluster.

Yaddehige et al. present GBRAP, a parser and database for analyzing RefSeq genomes. This publicly available tool offers over 200 metrics per genome element with flexible retrieval, visualization, and export options.

SatuTe by Manuel et al. is a new tool to quantify phylogenetic signal and saturation between subtrees. Applied to the Tree of Life, SatuTe shows that most ribosomal proteins support a eukaryotic clade.

Policarpo et al. use phylogenetic and synteny data to identify 19 teleost-to-teleost horizontal gene transfers in 11 orders, involving genes linked to immunity or pore formation; this suggests eukaryote-to-eukaryote HGT has shaped teleost evolution.

In Artemia franciscana, sex-biased gene expression and dosage compensation on the Z chromosome are linked to chromatin state. H4K16ac histone mark enrichment in female-limited Z chr. suggests a role in dosage compensation. New paper by Bett el al in MBE:

Lau et al. show that bioluminescent luciferases in brittle stars and octocorals evolved in parallel from haloalkane dehalogenases, highlighting how gene function and genomic availability shape convergent evolution.

Sign up now for a live discussion "From Elephants to Humans: Evolutionary Insights into Cancer" on Weds 22nd, 11am EST (4pm UK), hosted by ISEEC.

Amy Boddy (UCSB), Athena Aktipis (ASU) and me will explore how ecology, #evolbio and life history shape #cancer in humans and across the tree of life. Free registration: https://asu.zoom.us/meeting/register/VQxvtYAvQpaI53NdUy97XA#/registration
