Technical Abstract: Cultivated grapes and tomatoes have very different reproductive systems. While grapes are often outcrossed and grafted, tomatoes are generally selfed and propogated by seed. Large-scale public EST datasets were used in both crops to predict SNPs and PCR primers flanking these SNPs. Genomic DNA was amplified and the gene fragments were resequenced. These results were analyzed in each crop for the distribution of genetic diversity among cultivars and within genes. Frequency of intron discovery, SNP validation rates, and proportions of rare alleles reflect the different propogation histories of these crops.
