Dear GrainGenes User Community,

GrainGenes has been down for a while, and we realize the negative impact of this unavailability for your research. Thank you for reaching out to us while we were down. Thank you for your continuing support for GrainGenes.

We are still working on a long-term solution as to how we will serve the next version of GrainGenes. In the meantime, we have created a GrainGenes version from April 2025 on (unfortunately slower) machines so that you can have access to some of our data, tools, and services as soon as possible.

Note that this copy of GrainGenes is not perfectly working, and we are working on resolving these issues, and once we resolve them, the pages/connections will be immediately available to you. These are known major issues that we are working on:

• Report pages
• Search and Browse
• Oat Newsletter
• Pangenomes
• Along with other miscellaneous pages and services

We are also aware that the following services are extremely slow, and we are working to improve their speed:

• Genome browsers
• BLAST

Thank you again for your continuing support. Should you have any questions, please do not hesitate to reach out to me directly. You can also use the feedback button on top.
