October 2021: PepsiCo releases annotated gene set and associated files for OT3098 v2 genome in partnership with GrainGenes

Please see the more detailed Hot Topic description here
PepsiCo is releasing a set of predicted transcripts and translated protein sequences mapped to OT3098 v2 reference. Researchers are able to access the annotation file as a track on the genome browser. Additional files including a GFF, gene nucleotide fasta, ORF translated peptide fasta, and a text file with top BLAST hits are also available via the download site on GrainGenes.

October 2021: Aegilops tauschii Aet v5.0 genome browser and BLAST are available

Aegilops tauschii Aet v5.0 genome browser and BLAST service were created at GrainGenes based on Wang et al., G3, 2021

Aet v5.0 genome browser:
Aet v5.0 BLAST service:

BLAST database can be found at under "Wheat D Collections."

August 2021: MacGene files were added to the Wheat Gene Catalogue collection

MacGene files were added to the Wheat Gene Catalogue collection in GrainGenes at These are the files that were usually distributed in CDs in wheat conferences.

June 2021 Glaucousness Gene Class curated from the Wheat Gene Catalogue

Glaucousness is the visual expression of waxiness on the leaves and stem, and is the preferred term. Plants may be either 'waxy, glaucous' (the normal situation), 'waxy, non-glaucous' (e.g., Mentana), or 'low-wax, non-glaucous' (e.g., AUS 2598). The expression of glaucousness depends on the arrangement of wax deposits rather than the amount of wax (Johnson et al., 1983).

June 2021: Links to MASWheat updated for all pathology gene protocols

Marker Assisted Selection in Wheat (MASWheat) is a highly-curated site for PCR protocols in wheat research.

All pathology genes in GrainGenes with protocols at MASWheat are now up to date with links to the site. These are listed below. Please note that some pathology genes have several names reflecting their role in disease resistance. These are all listed, with links pointing to the first gene in the group.
