Deletion of wheat alpha-gliadins from chromosome 6D improves gluten strength and reduces immunodominant celiac disease epitopes
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

A high-quality genome assembly of the durum wheat landrace PI 192051. a Circular diagram showing the assembly features of PI 192051. The tracks, arranged from outermost to innermost, include: (i) chromosomes, (ii) GC content, (iii) gene density, and (iv) syntenic connections between A and B subgenomes. b Comparison of genome assembly quality (contig N50) between PI 192051and other published tetraploid (turquoise blue) and hexaploid (pink) wheat genomes. The horizontal axis represents the year, and the vertical axis represents the contig N50 size. Each circle represents one genome, with the diameter of the circle corresponding to the genome size. PI 192051 is highlighted with a red arrow. c Syntenic blocks among T. urartu (G1812 v2.0), T. monococcum (PI 306540), T. durum (PI 192051 and Svevo v1.0), T. dicoccoides (Zavitan v1.0), Ae. searsii (TE01), Ae. speltoides (TS01), and the A/B subgenomes of the bread wheat variety Chinese Spring (CS, RefSeq v2.1). Each line represents a syntenic block of 15 or more gene pairs with β₯ 80% identity.

Spatial cell clusters based on the expression of 99 genes analyzed by smFISH at three stages of wheat spike development.
Expression profiles of genes differentially expressed during spikelet development.
Weβre 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:
