Records for functional genes in wheat with reciprocal links to the 2018 IWGSC Chinese Spring RefSeq v1 were updated to accompany the publications of the book "The Wheat Genome" and the Watkins Collection reference "Harnessing Landrace Diversity Empowers Wheat Breeding for Climate Resilience" in preprint.

* 164 genes were curated from TWG-23-9 Rasheed A, Qayyum H, and Appels R (2023) The Wheat Genome. Chapter 9. Genome-Informed Discovery of Genes and Framework of Functional Genes in Wheat.

We have added a video tutorial that highlights a recent new feature that allows you to search for genes and transcripts across all of our genome browsers.

Taner Sen gave a general talk about GrainGenes at the IWGSC (International Wheat Genome Sequencing Consortium) Webinar series.

Three leaf rust QTL and nine KASP markers to assist in breeding are described in Xu et al (2024) Characterization of quantitative trait loci for leaf rust resistance in the Uzbekistani wheat landrace Teremai Bugdai. Phytopathology. First Look

As always, all curated data is linked to the reference file PHY-2024-Xu

KASP markers, gene and allele records, and germplasm records with links to GRIN are available for:

PHY-113-1979 Xu et al (2023) Identification of a Novel Pm65 Allele Conferring a Wide Spectrum of Resistance to Powdery Mildew in Wheat Accession PI 351817. Phytopathology 113:1979

We added Triticum urartu genome browser to our wheat collection, including BLAST databases for pseudomolecules, contig and proteins.

Publication: Ling et al. Nature, 2018

Triticum urartu (diploid, AA) is the progenitor of the A subgenome of tetraploid (Triticum turgidum, AABB) and hexaploid (Triticum aestivum, AABBDD) wheat. Genomic studies of T. urartu have been useful for investigating the structure, function and evolution of polyploid wheat genomes.

1,000 wheat exome SNP data were created as a track on the IWGSC Chinese Spring RefSeq v2.1 genome browser based on the Vasudevan and Cloutier, BMC Research Notes, 2023.

We added two wheat einkorn genome browser assemblies, including protein and nucleotide blast databases for each.
