Congrats to RootResponse lab members (CBGP) for this review in JXB
DOI: 10.1093/jxb/eraf520
how root traits, microbiome interactions, and epigenetic regulation play a role in plant heat stress resilience, stressing the need for lab approaches that closely reflect field-conditions

Next generation of 1001 Genomes Plus browser and data download Please indicate all features you would like to see in a browser that displays features of completely sequenced Arabidopsis thaliana genomes

We (Nordborg & Weigel labs) need input on the next generation of genome browsers & data download modes for the #Arabidopsis #1001GenomesPlus project. We have now a curated collection of over 500 long read genomes.

Please help us by filling out this questionnaire: docs.google.com/forms/d/e/1F...

New preprint from the lab on @biorxivpreprint.bsky.social! We show how SEPALLATA MADS-box genes in tomato functionally diverged to regulate inflorescence and floral organ development while maintaining redundant functions in conferring floral meristem identity.

🗣️ Today, José Jiménez Gómez from @cbgpmadrid.bsky.social came to visit us in Málaga to share his research with a great talk entitled “Metabolic adaptations towards salt tolerance in Arabidopsis plants from the Cape Verde Islands” as part of our #IHSMLaMayoraSeminars series

Amazing talk by @jimenezgomez.bsky.social at @ihsmumacsic.bsky.social

PhD advert

I recently moved my lab to Purdue University and am looking for graduate students. We are working at the interface of population genomics, quantitative genetics and functional genomics to understand how plants adapt to extreme environments. Reach out if you would like to discuss potential projects.

There are lots of answers out there that are beautiful because the truth of the system is beautiful. If I find one of these beautiful facts, it doesn’t make me brilliant. Just right place and right time. True scientific heroes acknowledge that fact.

📋 Join us on Friday 14th for a fascinating seminar with the researcher José Jiménez Gómez (@cbgpmadrid.bsky.social, Centro de Biotecnología y Genómica de Plantas). Don't miss it!

XVIII Meeting of Plant Molecular Biology I am going to attend the event

Save the date, 1-3 July 2026, for the XVIII Plant Molecular Biology Meeting #RBMP2026 in Bilbao. Check out the website for updates rbmp2026.com/RBMP/en/info

Out after peer review, collaborative study from Nordborg & Weigel labs with help from many others. Not the largest collection of new Arabidopsis thaliana genomes, but we hopefully put forward some good ideas for how to think about pangenomes and their analysis!

Getting a little salt tolerance Plants in a saline environment have no other choice than to adapt. Spanish and French researchers show one of those adaptions in the newly published research “Parallel evolution of salinity toleran…

Like I mentioned last week I like it when plants find a way against all odds. It is not just the perseverance and adaption. But also, that we can learn something from how those pioneering plants manage to survive against all odds. 🧵1/3

Parallel evolution in this case could be indicative of positive selection to produce the metabolite in this environment.
Indeed, plants carrying different alleles of GH38cv present different accumulation of the metabolite, and germinate, grow and reproduce better under high salt concentrations.

Looking at genome sequences from a global set of Arabidopsis plants (~1600), only two populations have non-functional aleles of GH38cv, and both come from the Cape Verde archipelago, but each population comes from a different island!
This is a case of parallel evolution!

We performed metabolite QTL analysis in a plant population derived from Cape Verde Islands (Cvi-0) and central Europe (Col-0).
The strongest QTL is in an unidentified metabolite.
We characterize the metabolite as glucuronyl-mannose, and we map the gene to a glycoside hydrolase family 38 (GH38cv).

Parallel evolution of salinity tolerance in Arabidopsis thaliana accessions from Cape Verde Islands Plants from the Cape Verde Islands evolved parallel mutations to protect from high salinity.

Our story about salinity tolerance in the Cape Verde islands is out in Science Advances! @science.org. Two independent mutations in the same gene conferred salt resistance to Arabidopsis plants!

Check it out here!

These were my very first experiments done at @cbgpmadrid.bsky.social. I still remember the excitement of @jimenezgomez.bsky.social and me when observing the plates and the shocking phenotype!
Thanks to all the authors for the work and so happy to continue working on this!

🧪Very timely, the paper from the story that @jimenezgomez.bsky.social explained us during #SEG2025 was published yesterday. Congrats to all the team and specially first co-author @laskotillean.bsky.social! Beautiful story! 🫶🏻

Composite image of map of North America, with route of travel. On the side are pictures of myself, Kevin, and a blooming monkeyflower.

Twenty years ago this month Kevin Wright and I set out on an 18,000 mile journey from Durham, NC across North America to collect monkeyflowers. The seeds from that trip (my third rotation project) have given rise to major advances and scores of scientific publications over the past two decades.

Lots of #arabidopsis mixed with the #tulips in the #JardinBotanico in #Madrid. I asked the local expert Carlos Alonso-Blanco: they likely came from Holland with the bulbs or the soil 🤦🏻
