Variation of presence/absence genes among Cucumis melo varieties

The sequenced melon reference genome belongs to the double-haploid line DHL92 derived from the cross between two phylogenetically distant melon cultivars: PI 161375 (Songwhan Charmi), subspecies agrestis, and the "Piel de Sapo" T111 line, cultivar group inodorus, of the subspecies melo. In order to study gene content variations that could be primarily responsible for at least part of the wide phenotypic diversity found within this species, the genome of two melon varieties were resequenced: C-836, an agrestis cultivar from Cabo Verde, and C-1012, a variety of the subespecies melo from Iraq. Paired-end libraries of average insert size 500 bp were built and sequenced using Illumina technology.
