After reading about milkweed’s cardiac glycosides in @nkwhiteman.bsky.social ‘s book, I was surprised to see people eating stew with milkweed floral buds in tonight’s episode of Tony Shalhoub Breaking Bread. Does the toxin break down in the heat? Or is it absent from buds?

Excited to share a recent review from our team in Physiologia Plantarum digging into how effectors modulate TPL/TPR family proteins through competition with endogenous EAR motif containing proteins: The TPX family of co‐repressors: a hub amidst the hubbub onlinelibrary.wiley.com/doi/10.1111/...

Really excited to share the pre-print of my first paper! It details the computational method we used to identify uncharacterized metabolites along the developmental gradient of maize roots, I hope you find it interesting! 🌱🌽

Standardizing models across a field so that everyone gets the same answer is only helpful if the answer is (1) correct and (2) generalizable. Otherwise it’s a regulated circle jerk.

Check out our new review in JXB: tinyurl.com/yta6fd5b @pablidopsis.bsky.social and I write about the cell's decision between division and differentiation. 🌱 What factors promote one or the other in different cell types? 🤔 Are they really mutually exclusive?

A friend of mine has a preprint out with an ingenious method to directly generate collections of NILs surrounding a locus or a collection of loci. They used the yeast KO collection, but it’d be cool to adapt for mapping traits in plants.

Did you know that there is a cell cycle duration gradient in plant root meristem? New story by joining forces between Plant dynamics lab and Crisanto Gutiérrez & Bénédicte Desvoyes lab @cbgpmadrid.bsky.social @cbm-csic-uam.bsky.social #Plants #roots #cellcycle www.nature.com/articles/s41...

Took some time off to visit family and to see Courtney Barnett for the first time this weekend. Amazing show! (Picture from @tbobrowsky.bsky.social blows all my phone-snaps out of the water.)

Here it is! Epidermal cells in the root can figure out if they are covered by the root cap or not using mechanical signals! Thanks to @ckirchhelle.bsky.social, @moritznowack.bsky.social, @nathan-german.bsky.social Annamaria Kiss and all the others!

Did America really need this product?

Ok, hear me out, here's the plan:

I love being a cell biologist, look at these beautiful cells! P. patens glam shot!

There is a nice News & Views article by @suruchiroy.bsky.social and others regarding our recent Nature Plants paper (@mestelle.bsky.social, @drannisr.bsky.social, and @luciastrader.bsky.social labs) and another from @dolfweijers.bsky.social 's lab. #PlantScience #Auxin rdcu.be/eAEnz

Our new work uncovering how WIND1 promotes somatic embryogenesis as a bifunctional chromatic regulator!!!! We knew WIND1 promotes new fate acquisition and now we show WIND1 also helps repressing existing identity!

😮 Just WOW!! Spray GFP mRNAs on plant leaves and the leaves translate this and you get glowing leaves. www.biorxiv.org/content/10.1...

How conserved are plant transcription factor binding sites? academic.oup.com/plphys/artic... Great study by @andreabraeutigam.bsky.social lab shows a mixed pattern. Thanks for making good use of #TAPscan onlinelibrary.wiley.com/doi/10.1111/... also. C2H2 neofunctionalization fits ny thoughts.

Hey all! We have been awarded a Spanish national grant to keep researching. Best of all is we have a full PhD contract assigned. We are looking for candidates interested in molecular biology and evolution of (plant) transcription factors, please spread the word!! Check our web for more information.

One of the best dinners and then seminar I've had was with Frank Stahl. He sat down with overhead projector and all the 200 in the audience felt they had a personal tutorial on DNA replication and his super-elegant research. RIP age 95. www.nytimes.com/2025...

Wow, I just heard that someone stole my mom’s hay field. She gave her neighbor permission to bale it, but, when he showed up to mow it, it had already been mowed, dried, baled, and hauled off.

Just learned that Frank Stahl (of the Meselson and Stahl DNA replication experiment ("the most beautiful experiment in biology") died at the beginning of April, to no fanfare. Here's a lovely video of them reminiscing: www.youtube.com/watch?v=7-tn...

Happy to announce that I will be opening my lab in the PMB department at UC Berkeley this July. Our lab will study nectary development and evolution using non-conventional models. We are actively recruiting. Join us if you are also enthusiastic about development or evolution!

I spoke with Jade Hindmon, host of @kpbssandiego.bsky.social Midday Edition, about the consequences of the current administration’s cuts to science funding. Please share to help spread the word and raise awareness. www.kpbs.org/podcasts/kpb...
