How do cells break symmetry to generate new shape and form? Using the apical hook as a model, we @joeecker.bsky.social applied spatial and single-cell multiomics, and identify a regulatory hotspot in a transient cell niche that drives this U-shaped structure 1/8 bsky.app/profile/bior...

Thrilled to announce our newest preprint on #dedifferentiation in Arabidopsis 🧬🌱. We used scRNA-seq and hormone treatments to track transcriptional reprogramming in diverse somatic cell types and found what we think is some pretty cool biology. Feedback welcome! www.biorxiv.org/content/10.6...

I eagerly await the reciprocal experiment www.nature.com/articles/d41...

Now online at @natplants.nature.com ‼️ Led by Jierui Zhao, a former PhD student @gmivienna.bsky.social & together w/ @moritznowack.bsky.social lab, we uncover how #autophagy shapes salt stress tolerance and lifespan. www.nature.com/articles/s41... www.nature.com/articles/s41... A short 🧵👇

Latest paper from the lab with several collaborators: We've built a four-dimensional spatial transcriptome atlas of barley grain development and germination, allowing detailed interrogation of where and when genes are expressed academic.oup.com/plcell/artic...

Our new experimental evolution study across 30+ locations using the plant Arabidopsis thaliana —— we direct "see" adaptation and extinction to different climates at the genetic as it happens! Read it in Science dx.doi.org/10.1126/scie... @ucberkeleyofficial.bsky.social @hhmi-science.bsky.social

We recently published a first story on combining spatial and single cell transcriptomics in barley (see here: www.nature.com/articles/s41...) Lets go for the next level now, i.e. understanding gene networks and barley meristem development in 4D!

The Bart Lab at UC Berkeley is looking for a postdoc. Please share!

New collaborative preprint out in which we use @10xgenomics.bsky.social Xenium to do some (a lot!) of plant spatial transcriptomics, led by Jim Whelan's team: "Mitochondrial Retrograde Signaling in Arabidopsis thaliana: heterogenous, spatial and polarised aspects" www.biorxiv.org/content/10.6...

New preprint! The same TFs can drive distinct regulatory programs depending on where they bind.
 TSS → rapid stress responses
 Intronic & upstream → cell-type programs
 Enhancer-like CRMs → embryo/meristem programs
 Coding-sequence binding → repression www.biorxiv.org/content/10.6...

We like to introduce map3C, developed by Joseph Galasso, that drastically improves the mapping and contact calling performance of snm3C-seq and now enables accurate 3D genome modeling. map3C was developed in collaboration with Jason Ernst and Frank Alber. www.biorxiv.org/content/10.1...

New pre-print from the team! The manuscript is @emma-raven.bsky.social's PhD work showing that whether a leaf is a carbon sink or a carbon source influences how they execute immune responses. Have a read! #PlantScience @johninnescentre.bsky.social

Thanks for the enthusiasm in using our online web browser! Due to the high traffic, we have allocated additional resources for user access, so if anyone encountered a bug with accessing the data, please give it a try again and reach out if additional errors are encountered!

a little secret- the actual amount of data produced and filtered using the Drosophila cell atlas standards was >800k but we more stringently filtered it to ~430k for all downstream analyses. We plan to make this additional 400k data availability in NCBI GEO and here arabidopsisdevatlas.salk.edu

Tremendous work by the extremely talented postdocs @TrALEE_Sci @NatanellaE @nobolly .Thank you for putting in a major effort on this “side project” to develop a powerful community resource arabidopsisdevatlas.salk.edu

From a gene’s single cell expression–through spatial localization–to novel function, and beyond! Now out @natplants.nature.com We built a comprehensive spatial-transcriptomic atlas of Arabidopsis, revealing cell-type identities across organs in unprecedented detail www.nature.com/articles/s41...

New OA Resource: "A single-cell, spatial transcriptomic atlas of the Arabidopsis life cycle" rdcu.be/eBmkU An extensive single-nucleus and spatial transcriptomic atlas of the Arabidopsis life cycle that represents 10 developmental time points in 6 diverse organs.

1/3 New preprint led by Shanshan Wang, in collaboration with the Timmermans lab. Several groups have presented sc/snRNA-seq analyses of Arabidopsis leaves after bacterial infection before. Is there anything left to discover? Turns out: Yes. #plantscience www.biorxiv.org/content/10.1...

Next up, a satellite meeting of #PlantBio2025, a celebration of the late great scientist, Joanne Chory share.google/xfOr0g8QkZ4A... Led off by Joe Ecker, and a list of her awards. She also trained a lot of people, see academictree.org/plantbio/tre...

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social‬ @erc.europa.eu‬ 1/x 🧵 www.nature.com/articles/s41...

Plants "bleed" too, but through gases! When wounded, ethylene leaks out and oxygen seeps in. This gas shift acts as an alarm, triggering self-repair to seal the breach. Excited to share our new collaborative work uncovering this clever plant mechanism! Excellent summary here, indulge! #plantscience
