Species: Seven Cucumis melo varieties
A team based in Spain and Italy last week (July 14) published the first comprehensive analysis of the genomes of several melon varieties in Molecular Biology and Evolution. Searching for genetic links to flavor, size, water usage, and other traits important for selective breeding of melons, the researchers identified 4.3 million single nucleotide polymorphisms (SNPs), plus other genetic variants linked to these traits, including duplications and mobile elements.
In all, the researchers found variations affecting 902 genes among seven melon varieties. They ascribed putative functions for 53 of the genes, including roles in disease resistance, cell-wall metabolism, and sugar metabolism. The researchers also found that wild melon varieties are the most genetically diverse.
