We are looking for a postdoc to help with a project on eelgrass genomics, in collaboration with the O'Connor and Rieseberg labs at UBC - see ad here tinyurl.com/2yd487p4! Come and join us in beautiful Vancouver 🌊🌾🏔️

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”

Building a pop genomics lab around selective sweeps in the DGRP dataset, but can't track down a VCF online. Federal funding casualty? Anyone know where to find a working link?

Excited to share our new preprint! 🍇🧬

We analyzed 639 genomes across 48 grape species to understand how hybridization drives adaptation.

• ~14% of average Vitis genome is introgressed

• Most parallel adaptations are shared via gene flow

• Two "hybrid species" are actually hybrid swarms

Huge congrats to @reginafairbanks.bsky.social who was just awarded a Chicago Fellows postdoctoral position to go work with @jmkreiner.bsky.social on the population genetics of adaptation in Amaranthus!

That’s freaking cool

Wow, what a loss for US science. But so glad you could find something that worked for you and your family. All the best Pleuni!

Massively parallel interrogation of the fitness of natural variants in ancient signaling pathways reveals pervasive local adaptation The nature of standing genetic variation remains a central debate in population genetics, with differing perspectives on whether common variants are almost always neutral as suggested by neutral and n...

One of the most exciting works of my career, years in the making. We used high-throughput precision genome editing to test the fitness effects of thousands of natural variants. Our findings challenge the long-held assumption that common variants are inconsequential.

Great new postdoc fellowship for foundational plant research.
If you’re into genetics and genomics of plant reproductive evolution or adaptive convergence (incl in the cool and charismatic nightshades!) I’d be happy to talk about possible projects!

Thanks Joey!!!

Would love your thoughts and comments, so please pass along if you have any to share 🙏😊

We also find more drought tolerance and stronger selection on drought alleles in agricultural compared to natural environments, highlighting how agricultural intensification and climate change interact to shape adaptation!

Herbarium specimens spanning over a century of changing climate, however, show evidence of fluctuating selection maintaining this adaptive variation. Drought alleles are selected for in hot, dry years but against in cooler, wetter periods

Ancestry mapping identified a highly polygenic basis of drought tolerance—with loci across nearly all chromosomes experiencing extreme selection and rapid allele frequency change across the length of an extreme drought event

Drought experiment setup in the greenhouse

We first combined a drought selection experiment with whole genome sequencing to uncover the genetic basis of drought adaptation in waterhemp across the landscape

Human-mediated land-use and climate change occur simultaneously, but how do they interact to shape adaptive dynamics? Super excited to share the first paper from the Kreiner lab, led by postdoc extraordinaire @rpineau.bsky.social

Join us tomorrow (30 Sept) at 14:00 BST to hear from 2024 #TansleyMedal winner Matthew Naish!

Matthew will be talking about unravelling plant centromeres in the telomere-to-telomere era.

This was a HUGE effort, taking years of diligent work. Hongfei was a true leader, and I'm really proud of this cool piece. We'd love any feedback y'all might have. www.biorxiv.org/content/10.1...

Congrats, James!!

Huntington's disease successfully treated for first time One of the most devastating diseases finally has a treatment that could transform lives, tearful doctors tell BBC

Wonderful news. A salutary reminder of the absolute benefits of scientific progress, and the absolute evil of conspiracist bollocks.

Fun to synthesize some exciting future directions for spatiotemporal genomics in this Tansley perspective.

Check er out!

I'll start reviewing applications in a little over 3 weeks for this PhD position. You could be doing fieldwork here! (or focus only on dry lab work if that floats your boat)

Would be excited to chat with folks looking for a postdoc in AI to develop models for genomic prediction...

A great opportunity for funding coming up soon is the Schmidt AI in Science fellowship, due October 13th! apply.interfolio.com/173322

Very excited to see this work in press! I think there is a reason to believe that this is a common means of stabilizing large-effect polymorphisms in general and might be an important reason for why diploidy is so common. news.stanford.edu/stories/2025...
