abstract: Simple sequence repeats (SSR) or microsatellites are becoming standard DNA markers for plant genome analysis and are being used as markers in marker assisted breeding. De novo generation of microsatellite markers through laboratory-based screening of SSR-enriched genomic libraries is highly time consuming and expensive. An alternative is to screen the public databases of related model species where abundant sequence data is already available. All the genomic sequences of Medicago from the public domain database were searched and analysed for di, tri and tetra nucleotide repeats. Of the total 156 000 sequences which were searched, 7325 sequences contained repeat motif and may yield SSR which will yield product sizes of around 200 bp. Of these, the most abundantly found repeats were the trinucleotide (5210) group. Except for a very small proportion (436), these link to the gene annotation database at TIGR (http://www.tigr.org). To facilitate further exploration of this resource, a dynamic database with options to search and link to other resources is available at (http://www.icrisat.org/text/research/ grep/homepage/genomics/medssrs1.asp) and on CDs from V.Mahalakshmi@cgiar.org
