PanViewer is a new GrainGenes tool currently under development that facilitates the exploration of pan-genes across wheat, barley, and oat genomes. PanViewer has been developed to provide researchers with an intuitive, user-friendly platform for visualizing and comparing pan-gene sequence diversity, gene presence–absence variation, and homoeologous relationships across major cereal crops. A total of 16 wheat genomes, 77 barley genomes, and 33 oat genomes have been processed using Pandagma, a method developed for pan-gene annotation that takes into account homoeologous chromosomes.

New curated barley data on GrainGenes include the following

QTL

QTL include original references, environmental notes, statistics, and positive allele notation. 

44 QTL from TAG-138:176 . Upadhaya, et al. (2025) Genome-wide association mapping of loci conferring all-stage and high-temperature adult-plant resistance to stripe rust in a global spring barley collection. TAG 138:176

GrainGenes has released a JBrowse v1 plugin that integrates BLAST search functionality, allowing users to BLAST genes, transcripts, or selected genomic regions directly from the genome browser with job tracking and history management.

FEATURES INCLUDE:

We have added Persephone links to 6 of our genome browsers.

Genome Browsers:

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/

Publication (Avni et al.): Nature - "A pangenome and pantranscriptome of hexaploid oat"

New Gene Records for Known Informative Markers.  See gene records for KASP primer links.

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. 

We added two new Quick Links on our home page: PanGenomes and Protocols. 

And we refactored the PanGenome Resources to improve accessibility of GrainGenes genomes and tools.
