Upshot: the pangenome is the inevitable solution to prokaryotic life under uncertainty. "Accessory" implies dispensable. The framework says they are essential, just not to every cell in every generation. A gene rarely needed is not a gene unneeded. It is insurance.

Happy 100th to a real one.

Excited to share my first preprint from my PhD w/ @justinmcrocker.bsky.social. We show that cell type-specific regulatory dominance promotes robustness and evolutionary innovation through interallelic transcriptional hubs, potentially expanding the mutational paths available to diploids. (1/18)

1/11 🔥 New preprint alert 🔥 We wanted to know what plants in the wild really care about. So we asked them 🎤. Here is what we learned: “Biotic-response networks are an important organizer of the transcriptome in wild Arabidopsis thaliana populations” www.biorxiv.org/content/10.6...

@pratikkatte.bsky.social and I just released Lorax 🌲, a tool for interactive exploration of biobank-scale ancestral recombination graphs (ARGs). If you’ve ever wanted to scroll across the ancestries of thousands of genomes… this is for you.

Recently we're working with SNPs from whole genome assemblies to estimate ARGs. It's a pain to go from alignment files to vcf, keeping track of masked and invariant sites. So we wrote a snakemake/SLURM pipeline. Hope it's useful to others, and don't hesitate to post issues if there are problems!

We are very excited to share a new resource from our team: spatial subcellular proteome maps in plants! We developed an MS-based method that registers localizations of about 8000 proteins in Arabidopsis roots in a single experiment. (1/9) www.biorxiv.org/cgi/content/...

“Aneuploidy was identified in inbreeding and outbreeding populations of cultivated potato, with frequencies ranging from 14.8 to 24.0%, indicating notable genomic instability.” Plant genomes tolerate instability—more akin to human tumor evolution than stability. www.science.org/doi/10.1126/...

Heya science peeps, my first first-author paper is on Biorxiv! We show how transcriptome-wide expression variability in outbred animals responds massively to an environmental stressor and is underpinned by cryptic variability- (not just mean-) controlling alleles. www.biorxiv.org/content/10.6...

This article is now published! academic.oup.com/nargab/artic... We’ve added a few new analyses. First off, we show that, while gene presence absence variation (PAV) scales with evolutionary distance in both plants and animals, the base level and rate of accrual are both twice as high in plants.

I had intended to post something about this new Google DeepMind paper that appeared yesterday in Nature, but the press coverage has added to what there is to say. So this is a long 🧵 www.nature.com/articles/s41...

If you’ve heard me talk in the past ~5 years, you will know I have developed an obsession with acrocentric chromosomes. This is all of that, condensed into one paper. I will do a full thread in the new year, but for those that want something to read over the holidays, have at it. Such a cool story!

Our new preprint is out: www.biorxiv.org/content/10.6... We show that GRN benchmarks commonly used can overestimate performance due to negative-sampling choices, sometimes allowing simple degree-based baselines to rival more complex GNNs. A reminder of why bias-aware evaluation matters!

I've been thinking about the "virtual cell" concept and wanted to write up a few thoughts. Specifically on how I think the prior experience in GWAS informs the most likely way these models will be useful. andrewcarroll.github.io/2025/12/23/t...

We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen. 1/n
