Area of Science:

  • Plant genetics
  • Bioinformatics
  • Genomics

Background:

  • GrainGenes serves as the primary international database for wheat, barley, rye, and oat genomes.
  • It is a crucial repository for genetic information, including maps, probes, primers, genes, alleles, and quantitative trait loci (QTLs).

Purpose of the Study:

  • To provide a comprehensive and integrated resource for the genetics and biology of cereal crops.
  • To facilitate the contribution and retrieval of diverse genetic and genomic data.

Main Methods:

  • Data curation and integration from the research community and external databases.
  • Linking records with sequence and bibliographic information, including BLAST searches of expressed sequence tags (ESTs).
  • Interfacing with other major databases like Gramene, TIGR's Gene Indices, and GenBank.

Main Results:

  • GrainGenes hosts detailed documentation on primer sequences, polymorphism descriptions, genotype and trait data, experimental protocols, and phenotype photographs.
  • The database integrates curated data with sequence and bibliographic records, and EST data.
  • The GrainGenes homepage offers additional community resources such as publications, datasets, specialized databases, and coordination pages for research efforts.

Conclusions:

  • GrainGenes functions as a vital central point for accessing and contributing information on cereal crop genetics.
  • It supports cooperative research through various community resources and data integration.
