Abstract Background Tomato species are of significant agricultural and ecological interest with cultivated tomato being among the most common vegetable crops grown. Wild tomato species are native to diverse habitats in South America and show great morphological and ecological diversity that has proven useful in breeding programs. However relatively little is known about nucleotide diversity between tomato species. Until recently limited sequence information was available for tomato preventing genome-wide evolutionary analyses. Now an extensive collection of tomato expressed sequence tags ESTs is available at the SOL Genomics Network SGN . This database holds sequences from several species annotated with quality values assembled into unigenes and tested for homology against other genomes. Despite the importance of polymorphism detection for breeding and natural variation studies such analyses in tomato have mostly been restricted to cultivated accessions. Importantly previous polymorphisms surveys mostly ignored the linked meta-information limiting .
