High-resolution genetic map for understanding the effect of genome-wide recombination rate on nucleotide diversity in watermelon.
Bottom Line: We assessed the genome-wide variation in recombination rate (GWRR) across the map and found an association between GWRR and genome-wide nucleotide diversity.LD decay was estimated for various chromosomes.We identified a strong selective sweep on chromosome 3 consisting of important genes that might have had a role in sweet watermelon domestication.

Mentions: We examined the collinearity of genetic and physical maps for various chromosomes (Figure 4). Markers on chromosomes 3, 5, 7, and 10 were highly co-linear in terms of physical location. Chromosomes 1, 2, 4, 8, and 9 moderately agreed with the watermelon reference sequence. Chromosome 11 showed the highest disagreement between the genetic and physical map on either side of the chromosome; it contained a large segment that was not collinear with the physical map. We observed 17 major genome rearrangements or disagreements across all chromosomes.
