A graphical view of the melon genome sequence improvement. A Map of the DHL92 Illumina PE reads against the reference genome (DHL92, CM3.5 version) on the region containing genes MELO3C004311 to MELO3C004313. Three major gaps mark the position of stretches of Ns in the reference genome, one of which causes gene MELO3C004312 to be partially annotated. Colored vertical lines above the coverage track signal discrepancies between the aligned reads and the reference genome. B Mapping of DHL92 Illumina PE reads against the improved reference genome. The main gaps were closed and the number of discrepancy lines greatly reduced. Figure produced using IGV software.
