GrainGenes Updates

February 2024 : Leaf rust QTL and KASP markers in the Uzbekistani wheat landrace Teremai Bugdai were curated

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

December 2023: Added Triticum urartu genome browser and BLAST

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.

 

September 2023: Genome browsers and BLAST service are available for Einkorn assemblies in a brand-new site

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.

September 2023: A new track is added placing Oat-2018-Consensus (2018 Mrg) map regions on the OT3098 v2 genome assembly

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).

August 2023: GWAS results for pathology, salinity, and agronomic traits added to the IWGSC Chinese Spring v1 browser

Three new tracks have been added to the IWGSC Chinese Spring v1 genome browser aligning QTL and significant markers for salinity, pathology, and agronomic traits.

All QTL have records in the GrainGenes Database with reciprocal links to and from the browser.

Please see individual papers for QTL statistics and additional information.

Salinity Tolerance Traits

July 2023: 181 Wheat QTL for agronomic traits under organic and conventional practices.

181 agronomic QTL were created from 354 marker-trait associations (MTAs) in Semagn et al. (2022) Genome-wide association mapping of agronomic traits and grain characteristics in spring wheat under conventional and organic management systems. Crop Science 62:1069 doi.org/10.1002/csc2.20739. MTAs within ~20MB of each other were combined into one 'QTL' for this curation.

March 2023: Barley Gene links to NordGen updated

Links to the International Database for Barley Genes and Barley Genetic Stocks created by Udda Lundqvist and Jerry Franckowiak and currently maintained by NordGen have been updated for over 600 barley genes in GrainGenes.

Records in the Intl' Database contain a wealth of inheritance and mutation information, photos and descriptions of mutants, and comprehensive reference lists.

Example of GrainGenes records with new links are below:
