The Gramene Genetic Diversity Module: a resource for genotype-phenotype association analysis in grass species

The Genetic Diversity module of the Gramene database ("http://www.gramene.org/diversity":http://www.gramene.org/diversity) is specifically designed to handle data from high-throughput sequencing and array-based genotyping plateforms. Empowered by the Genomic Diversity and Phenotype Data Model, Gramene Genetic Diversity module provides live database connectivities of RFLP, SSR and SNP allele data, information about QTL, passport data for wild and cultivated germplasm from rice, maize, wheat, and Arabidopsis, and quantitative phenotypic data for some of these accessions. Large datasets of SNP variation are searchable via genomic positions of interest by SNP Query tool on a sequenced genome; and, trait associations, patterns of linkage disequilibrium and diversity can be evaluated using TASSEL. The Gramene database is updated twice a year, with the most recent release (Build 31) completed in May 2010.
