GrainGenes is an international database for genetic and genomic information on Triticeae species like wheat and barley. This resource serves as a vital hub for researchers, facilitating crop improvement through curated data and integrated genomic information.
Area of Science:
- Agricultural Science
- Genomics
- Bioinformatics
Background:
- GrainGenes is a key international database for genetic and genomic data.
- It covers Triticeae species (wheat, barley, rye) and oats, including wild relatives.
- The database functions as both a data repository and an information hub for the research community.
Purpose of the Study:
- To describe the GrainGenes database and its role in genetic and genomic research.
- To highlight the migration to an integrated relational database in 2004.
- To provide perspective on how genomic databases accelerate research and crop improvement.
Main Methods:
- Intensive curation of genetic maps, physical maps, probes, genes, and quantitative trait loci.
- Partially automated curation of literature references, sequences, and inter-database links.
- Development of unique BLAST datasets for Triticeae research, including mapped sequences and repetitive elements.
Main Results:
- GrainGenes provides curated genetic and genomic data for key crop species.
- The 2004 migration enhanced database delivery through an integrated relational system.
- The website offers specialized databases, informational topics, and downloadable files.
Conclusions:
- GrainGenes serves as a crucial resource for researchers studying Triticeae and oat genetics.
- The integrated database structure facilitates efficient access to genomic information.
- Genomic databases like GrainGenes are essential for advancing crop improvement strategies.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
