Transcriptomic Temperature Stress Responses Show Differentiation Between Biomes for Diverse Plants Abstract. Plants are foundational to terrestrial ecosystems, and because they are sessile, they are particularly reliant on physiological plasticity to res

How do plants from different environments handle temperature extremes? Andrew et al. studied 20 Australian species and found conserved gene expression responses to heat and cold (with biome-specific differences).

Genes Encoding Intracellular Signaling Proteins in Animals Originated Along with Metazoa and Chordata: Chance or Necessity? Abstract. In this work, we investigate whether the construction of signaling pathways during evolution follows a deterministic law through a study of the e

10 months ago

Do signaling pathways evolve in a predictable order? Picolo et al. studied 47 pathways across 315 animal species, finding little evidence for a universal link between gene age and pathway position - this suggests stochastic pathway evolution.

Estimates of the Mutation Rate per Year Can Explain Why the Molecular Clock Depends on Generation Time Abstract. Rates of molecular evolution are known to vary across species, often deviating from the classical expectation of a strict molecular clock. In man

10 months ago

New paper by Lewin & Eyre-Walker finds a strong negative correlation between generation time and yearly mutation rate. This highlights generation time as a key driver of molecular evolution across eukaryote clades.

Localized Tissue-Specific Gene Expression and Gene Duplications are Important Sources of Social Morph Differences in a Social Bumblebee Abstract. Understanding the expression of multiple behaviorally and morphologically distinct phenotypes from a single genome represents a fundamental topic

10 months ago

Queen–worker differences are linked to gene duplication and differential gene expression, in particular in reproductive tissues. Study by Xu & Colgan sheds light on how social insects resolve genomic conflict to produce distinct castes.

Horizontal Transfer of Bacterial Operons into Eukaryote Genomes Abstract. In prokaryotes, functionally linked genes are typically clustered into operons, which are transcribed into a single mRNA, providing for the coreg

11 months ago

Bacterial operons may persist in eukaryotes (e.g. fungi) after horizontal gene transfer, according to Kogay et al. Operon-derived gene pairs suggest initial neutral retention and later functional integration or degeneration.

Coppage et al. identify four ancient polyploidy events with unusually high duplicate gene retention. Elevated gene conversion and delayed diploidization suggest a distinct class of paleopolyploid genomes.

Comparative transcriptomics of nematodes C. elegans and Brugia malayi supports Ohno’s hypothesis of X-linked genes showing upregulation following Y degeneration, which depends on the dosage-sensitive gene content of proto-X.
