An update to our spatial transcriptomics study of the wheat spike is now available in bioRxiv! The updated version includes functional validation of the roles associated with the specific expression patterns of LFY in intercalary meristems, SPL14 in inflorescence meristems, and FZP in glume axillae.

🌱From Crop Science: New wheat lines combining Yr78 with other resistance genes cut stripe rust severity, offering stronger, multi-gene protection for breeders.

Our lab recently published "Durum wheat with Yr78 and common wheat with Yr78 and Yr36 in coupling show enhanced stripe rust resistance"

The federal government's $1B dollar demand from the University of California is designed to devastate public Universities and their critical mission. Our lab will #StandUpForUC to defend one of America’s greatest public university systems and support this life-saving work. ucal.us/standupforuc

Talking Biotech 467 - #Celiac safe wheat? Less immunoreactive wheat has been developed by @UCDavisPlants using old-school mutagenesis. A scintillating talk with grad student Maria Rottersman. @ASPB share.transistor.fm/s/9419052e

🎙️ Just published a new episode of Talking Biotech with Dr. Kevin Folta: Old Tricks, New Wheat for Celiacs - Maria Rottersman. Have a listen:

🌱 From UC Davis: Deleting key gliadin genes boosts wheat gluten strength & cuts celiac-triggering epitopes—without harming yield. (Maria Rottersman, Jorge Dubcovsky) ▶️ www.ucdavis.edu/food/news/ta...

New work from a graduate student, Maria Rottersman, and others in the lab demonstrates that deleting the alpha-gliadins on chromosome 6D of wheat improves gluten strength and produces less celiac disease epitopes. Check it out now in Theoretical and Applied Genetics: rdcu.be/egXZ2

🌱From a Nature Portfolio preprint: Cloning of Lr30 reveals it’s identical to Lr.ace-4A and encodes a unique NLR gene conferring strong rust resistance in durum #wheat, but less so in hexaploid. (Jorge Dubcovsky) ▶️ www.researchsquare.com/article/rs-6... #PlantScience #PlantImmunity

Please read this statement supporting science from members of US National Academies of Science, Engineering, and Medicine. It’s important we stand against these egregious cuts to science.

Check out this article by a previous lab member, Iago Hale, on the impact of cuts to the USDA germplasm system. Definitely worth a read! www.nytimes.com/2025/03/22/o...

Check out our work on fine-tuning miRNA control of plant height in wheat and triticale, as covered by the folks at the plant sciences department! www.plantsciences.ucdavis.edu/news/deberna...

#PlantSci Research Weekly March 7 plantae.org/plant-scienc... (2/2) Single-cell analysis of wheat spikelet; Autoactivated calcium channel enhances symbiosis; Fungal pathogen hijacks phosphate signaling; Erucamide inhibits the type III secretion system; How Rhodanobacter R179 evades plant immunity

We’re excited to share our new preprint on wheat spike development! We used spatial transcriptomics and scRNA-seq to take a closer look at the different cell types and expression domains during key developmental stages of the wheat spike. Check it out here: www.biorxiv.org/content/10.1...

🌱 A wheat-rye chromosome rearrangement alters Mg partitioning between shoots and roots by increasing jasmonate biosynthesis, enhancing wheat tolerance to Mg scarcity. (Gilad Gabay, Jorge Dubcovsky) ▶️ www.sciencedirect.com/science/arti... #PlantScience #Genomics #Wheat

Congrats @cristobaluauy.bsky.social, incredible news!

We’re excited to announce the recent publication from our lab was featured on the cover of the plant biotechnology journal! It demonstrates an approach for precisely controlling wheat and triticale plant height. Read the full paper here: onlinelibrary.wiley.com/doi/10.1111/...
