Fragmented landscapes of mobile transposable element families bolster the diversity of large-effect alleles in Arabidopsis https://www.biorxiv.org/content/10.64898/2026.10.12.758581v1

I’m so tired of US politics, I propose we abolish existing states and make new ones based on the ancient Cicada brood territories.

🚨Our new preprint is out! 🤩 🌟 Mutation rates vary widely across taxa, and decades of research have sought to explain why. ♀️♂️ Reproductive modes, and evolutionary shifts between them, could help explain some of this variation. ❓ So what does the evidence tell us? 👀 Read our preprint to find out!

Fun to see Senator Slotkin learning about the Michigan Monkeyflower. It is a great community in Michigan that has built up around protecting and studying one of the state's only endemic plant species.

One of the best parts of visiting Beaver Island, the most isolated inhabited island in the lower 48, is learning about the rare plant species that grow here.

I've accepted that Mimulus will never beat cult allegations (that I have directly perpetuated) But hey, like any good cult, we always love new members!

Good morning, #SMBE2026! To purge, or not to purge, *that* is the question 🧬 I'll be giving a talk on how mating system transitions shape transposable element dynamics in monkeyflowers this morning in S24 at 11:20 AM - come for the Hamlet pun, stay for the cool comparative genomics!

Time for an experiment! You know those cute little roadside stands with honors-system eggs or produce? Look, I know I live in "big scary Philadelphia oooh 👻" but I'm gonna try it. What's the worst that can happen? Thieves create habitat for native bees? Jokes on them! I wanted them to do that!

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.

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...

I mean, true.

NSF - Forced reorg - POs down ~ 40% (DRP, most rotators not renewed, retirements) - Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …) I personally love the boxes they gave us for packing. “Details matter” 🙃

We are hiring at California Botanic Garden! The Restoration Intern will have the opportunity to work on a variety of projects involving out-planting, seed collection, plant propagation and monitoring. This is a full time temp position (6 months) that can be extended. Please share! lnkd.in/gaNuNGxA

In these field experiments we did earlier this year in the town of Iijima, we found that spraying nectar yeast and bacteria to buckwheat fields increased insect pollination and seed set.

A distinguishing character of Monarda fistulosa and its close relatives is a fun tuft of hairs at the top of the upper corolla lobe. Endearingly it persists all through flower development (and is arguably even more fun in the early stages)

Are you from one of these states? Then we need your help to save American science! The Senate Appropriations Committee will be marking up the President's Budget Request for science on Wednesday. People have been saying the proposed cuts "decimated" US science, but that's wrong: they are apocalyptic
