Our lab has just posted a review on wheat spike development, with an emphasis on the regulation of the number of spikelets per spike on bioRxiv.
Regulation of spikelet number during wheat spike development
Wheat produces unbranched inflorescences (spikes) composed of smaller inflorescences (spikelets) as their fundamental building units. The spikelet number per spike (SNS) is a major determinant of grai...

Our manuscript on the role of the SPL genes and the endogenous age pathway on wheat heading time is now available in bioRxiv! www.biorxiv.org/cgi/content/...
Our Genome Biology paper on wheat spike development integrating single cell and spatial transcriptomics is now published! Check out the paper here: doi.org/10.1186/s130... and enjoy the beautiful pictures (including our 44 supplementary figures)! Be sure to check out some of our tools below!
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.
Spatial and single-cell expression analyses reveal complex expression domains in early wheat spike development
Wheat is important for global food security and understanding the molecular mechanisms driving spike and spikelet development can inform the development of more productive varieties. In this study, we...

🌱 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...
Targeting Gluten: Researchers Delete Proteins in Wheat Harmful to People with Celiac Disease
A UC Davis study found that deleting a cluster of genes in wheat may reduce wheat allergies without harming breadmaking.
