The soybean (Glycine max L. Merr.) has developed into a reference species complete with a full set of genomic resources. Several Bacterial Artificial Chromosome libraries have been produced and physical maps have been assembled in genotypes representing both Northern and Southern germplasm. High throughput sequencing has already been applied to transcript profiling . A very large Expressed Sequence Tag (EST) collection has been developed. These ESTs have been evaluated to demonstrate that the soybean genome has undergone at least two rounds of large-scale duplication events. Soybean has one of the most dense molecular maps of any crop species. Molecular markers include RFLPs, SSRs and SNPs. The GeneChip by Affymetrix is being used to identify additional markers and measure global gene expression. The USDA public databases, SoyBase and The Soybean Breeders Toolbox, provide access to map-based and sequence-based data, as well as germplasm information. More recently, the databases are providing genome browser interfaces to access the whole genome sequence assembly and annotation.
