Single nucleotide polymorphism analysis of the endopolygalacturonase gene in peach and its potential use in crossbreeding programs
Single nucleotide polymorphisms (SNPs) are the most abundant sequence variations found in plant genomes and are widely used as molecular genetic markers in genetic diversity studies and crossbreeding programs. In this study, we examined 113 DNA sequences of the endopolygalacturonase (endo-PG) gene from 67 peach accessions and found a total of 56 SNPs and 6 insertion/deletions (indels), with a frequency of 3, 1, and 3% for the transitions, transversions, and indels, respectively.
