How to Use GDR, the Genome Database for Rosaceae

The Genome Database for Rosaceae (GDR, http:/ ww.rosaceae.org) is the long-standing central repository and data-mining resource for genomics, genetics, and breeding data of Rosaceae, an economically important crop family that includes almond, apple, blackberry, cherry, peach, pear, plum, raspberry, rose, and strawberry. GDR contains whole genome sequences and annotation, unigenes for the family and the genera, gene sequences from NCBI, genetic maps, trait loci, germplasm, marker diversity, breeding and publication data. The predicted genes of the whole genome sequence, unigenes and NCBI genes have been further annotated by homology to genes in other species, InterPro protein domains, GO terms and KEGG pathway terms. Whole genome sequences and annotation including genes, mRNAs, markers, re-sequencing data, NCBI sequences and homologous genes from other species, can be viewed through GBrowse. Pathway data can also be accessed through the GDR Cyc Pathways databases and synteny among the three sequenced genomes can be viewed through GBrowse_Syn. Major effort on curating genetic maps and trait loci has been underway and GDR now contains extensive qualitative and quantitative trait loci and genetic map data. In this computer demo, we will update the users with the new data and functionality and demonstrate how to use GDR through use of specific exercises.
