Purpose of the Study:

• To provide a comprehensive overview of the curated content and tools available in GrainGenes.
• To highlight the evolution and expansion of GrainGenes resources over time.
• To emphasize the utility of GrainGenes for researchers, growers, and farmers.

Main Methods:

• Curated data collection and integration for multiple cereal crops.
• Development and implementation of web-based tools for data access and analysis.
• Continuous updates to include genomic sequences, assemblies, annotations, and pangenomes.

Main Results:

• GrainGenes offers a centralized repository of genetic markers, maps, genomic sequences, and pangenomes.
• A suite of web-based tools enhances data accessibility and utility for diverse users.
• The database has evolved significantly since its inception, expanding its scope and capabilities.

Conclusions:

• GrainGenes is an invaluable resource for plant researchers, geneticists, and breeders.
• The database supports efforts to improve crop traits like resistance and nutritional content.
• Its resources contribute to developing more nutritious food and high-quality animal feed.
