Recently, whole genome sequencing in cucumber [42]and the availability of large numbers of molecular markers[43] has made it possible to define more clearly the syntenic relationships between cucumber and melon. By alignment of 348 marker sequences mapped in the melon genome onto the 9930 cucumber draft genome, Huang et al. [42] found that there was no substantial rearrangement between cucumber Chromosome 7 and melon Chromosome I. In addition, the majority of cucumber Chromosome 4 corresponded to melon Chromosome VII, and each of the remaining five cucumber chromosomes was collinear to two melon chromosomes mapping study by Fukino et al. [44], who placed 70
cucumber SSR markers on a melon linkage map.
[42]. The correspondance between melon and cucumber
chromosomes was also observed in a comparative
