Lastly, I want to highlight that this paper was published with eLife's new pub model and we had a great experience.

The genetic control of rapid genome content divergence in Arabidopsis thaliana

Repeat variation in wild Arabidopsis thaliana arises from centromere-proximal sequence changes and rare variants in DNA replication, repair, and methylation genes, consistent with purifying selection ...

Finally, the GWAS hits were enriched for rare alleles, suggesting purifying selection constraining repeat expansion and contraction. We look forward to seeing if our results are unique to Athal or reflect plant genome evolution more generally. 6/7 elifesciences.org/articles/108...

The potential trans-regulators of repeat CNV were enriched for genes involved in DNA replication, repair, and methylation. This suggests natural variation in mutational machinery likely regulates repeat dynamics (and thus genome evolution)! 5/7 elifesciences.org/articles/108...

We treated repeat CN like a phenotype and did GWAS. Most repeat CNV mapped in-cis to pericentromeres, where repeats are clustered in the Athal genome. However, we also found several common hits potentially regulating repeat CNV in trans. 4/7 elifesciences.org/articles/108...

The vast majority of repeats had CNV in the pop. By our estimate, repeat expansions were much more common than repeat contractions. Perhaps unsurprising to the Athal community, accessions from Sweden & Africa were the most diverged compared to everything else. 3/7 elifesciences.org/articles/108...

The k-mer method is ref. free, but can be used to est. copy number of a given sequence, e.g. a canonical repeat. Although not as good as a full assembly, this could be a cost effective way to measure CN in many samples with low coverage or reanalyze NCBI SRA 2/7 elifesciences.org/articles/108...

Friends, please help spread the word about our microbiology REU program at Montana State University. www.montana.edu/mbi/reu/ Each student receives a stipend ($7000 for 10 wks). Travel compensation, room, and board are also provided. Details in the attached pic--Feb 14 deadline 🧫🧪🦠#microsky

This Research Experiences for Undergraduates (REU) program is funded by the National Science Foundation to create "points of entry" for students interested in research. Students apply from across the country to spend 10 weeks in Bozeman, Montana this summer (May 26, 2026 - August 1, 2026). Admitted students are paired with a faculty mentor, who serves as an advisor for a student's summer project. Each student receives a stipend ($7000 for 10 wks). Travel compensation, room, and board are also provided.

Our program leverages MSU’s unique microbiology expertise, focusing specifically on microbes living with little or no oxygen (like those in the hot springs of nearby Yellowstone). Low oxygen microbes are essential to human and ecosystem health. They influence (or control) such processes as the breakdown of food in the GI tract, removal of toxins from our bodies and the environment, and production of greenhouse gases. They are also models for understanding the origins of life on this planet, and the potential for life on other planets.

A key goal of our program is to recruit students from schools with limited research infrastructure. Being in Montana, a state with a vibrant Native American community, we are particularly interested in applications from students at tribal colleges. However, ANYONE with an interest in microbiology - or biology/science in general - can and should apply.

If willing and able, please share/tweet/spread the word far and wide. Applications are due February 14, 2026. Full details can be found through our website http://www.montana.edu/mbi/reu/
