The GSP: Genome Specific Primers tool is deployed in GrainGenes through graingenes.org site at https://graingenes.org/GSP/. GSP is "a web-based platform to design genome-specific primers that distinguish subgenome sequences in a polyploid genome." The site was not accessible for a while to ensure IT security.
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.
We added Triticum timopheevii to our genome browser collection, including BLAST databases.
The journal article is currently in press: Grewal et al., Nature Scientific Data, 2024 (in press). We will create a link from this page once the article is published.
The Triticum turgidum Durum Wheat Svevo Rel. 2.0 pseudomolecules (2024) is made available under the prepublication data sharing principle of the Toronto agreement (Toronto International Data Release Workshop Authors. Prepublication data sharing. Nature 461, 168–170 (2009) https://doi.org/10.1038/461168a).
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
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.
GrainGenes is working to provide a resource to reflect the growing collection of KASP primer sets developed to distinguish allele states of important traits in the small grains.
The journal article “Einkorn genomics sheds light on history of the oldest domesticated wheat” was published.
Key message: This manuscript describes a high quality genome of world oldest cultivated wheat "Einkorn wheat" and its potential in future wheat improvement.
Defining the locations of cM regions from the Oat-Consensus-2018 (2018 Mrg) map on the OT3098 v2 sequence
This genome browser track accompanies the article “One hundred years of comparative genetic and physical mapping in cultivated oat (Avena sativa L.)”, by Wight, et al. (2023) (under review).
