Regulatory features determine the evolutionary fate of laterally acquired genes in plants Abstract. Lateral gene transfer (LGT) is widespread in eukaryotes, including in animals and plants where it can fuel adaptive evolution and innovation. How

Awesome to see @cfcollins.bsky.social first paper out from her PhD - a huge amount of work!!

Collins et al. combined expression, methylation, and genomic data to investigate long-term persistence of laterally acquired genes in the grass Alloteropsis, showing that those capable of regulating their own expression are more likely to persist.

Graphic announcing new AJB Synthesis article by Haley Branch.

Methodological illustration for asking whether X affects plants. “Question” provides an example of a question that both ecologists and evolutionary biologists ask, with categories of traits often of interest. “Experiment” shows trait examples and comparisons (populations, environmental, across time). Types of traits are where evolutionary biologists could expand their breadth. “Outcome” describes lasting effects of whether X affects traits to the point that it is passed on and contributes to future generations or it leads to extinction. “Outcomes” is where ecophysiologists could expand their work.

@oso-tee.bsky.social Congrats 🔥

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

Adaptation is less accessible through mutations in promoters than in coding sequences when large effect sizes are needed Mutations within promoters and coding sequences are both involved in adaptation, but their relative contributions remain to be compared directly. Using the fungal enzyme cytosine deaminase, we examine...

Really excited to share our latest paper led by @simonaube.bsky.social. Fascinating results examining whether regulatory mutations can lead to adaptation as fast as coding mutations do. #mevosky #evobio #evoSky

pangenome 'expansion' curves for cotton and soybean

Determining presence-absence variation (PAV) across reference genomes is a major goal of pangenome analysis. It turns out that A LOT of gene PAV is due to methodological artifacts.

We explore the causes of this in soybean and cotton datasets in our recent preprint: www.biorxiv.org/content/10.1...
