GrainGenes Updates

February 2026: SNPversity 2.0 with diverse wild barley (Hordeum vulgare ssp. spontaneum) accessions added on GrainGenes

February 2026: SNPversity 2.0 with diverse wild barley (Hordeum vulgare ssp. spontaneum) accessions added on GrainGenes. The web-based tool facilitates access to variant data and visualizing genetic diversity and is accessible through https://graingenes.org/snpversity/

September 2025: FoldSeek Search Tool added for the predicted AlphaFold2 database structures of Triticum aestivum, Triticum turgidum, and Hordeum vulgare

We added the FoldSeek Search Tool for AlphaFold2 structures of three pre-calculated genomes searched against six genomes.  The predicted AlphaFold2 database structures for Triticum aestivum (139,466 proteins), Triticum turgidum (181,745 proteins), and Hordeum vulgare (195,130 proteins) were each aligned against six proteomes (T. aestivum, T. turgidum, Triticum urartu, H. vulgare, Aegilops tauschii and Arabidopsis thaliana) using the software FoldSeek.

July 2025: New YouTube video tutorials for contributing projects: WGC at Komugi and MASwheat from UC Davis

The GrainGenes project acquires information primarily from published data, but also relies on curation from other small grains projects.  

Two new YouTube videos were created to highlight these resources.

Wheat Gene Catalogue at Komugi describes the online database from the Wheat Gene Catalog through 2013, an important resource for historical wheat genes and cultivars containing favorable alleles. 

July 2025: International Barley Genetics Symposium 14 (2024) Program and Abstracts are available.

International Barley Genetics Symposium (IBGS) 14 took place in 2024 in Rosario, Argentina. A combined pdf file of the program and abstracts is now available under Barley Boulevard along with other IBGS abstracts.

February 2025: Breeders Meta QTL for yield and yield-related traits in barley

25 Breeders Meta QTL from PLoS 19:e0303751 .   Du, et al. (2024) Genome-wide screening of meta-QTL and candidate genes controlling yield and yield-related traits in barley (Hordeum vulgare L.)

QTL are described for (GMT) grain morphological traits, (GN) grain number, (SRT) spike-related traits, (GW) grain weight, (GY) grain yield, (GPT) growth period traits, (BY) biomass yield, (TN) tiller number, (PH) plant height, (HI) harvest index, (GFRT) grain filling-related traits.

February 2025: Wheat and MASWheat protocols for the small grains compiled on GrainGenes

Protocols from John Innes Center (I. Faci-Gomez and C Uauy) have been contributed to the GrainGenes collection of protocols. These are available at protocols.io and include : 

How to grow wheat

Wheat inflorescence meristem micro-dissection 

Nuclei isolation from wheat meristems

Wheat high molecular weight DNA extraction 

RNA extraction from wheat stigmas
