Draft genome sequences of two oriental melons, Cucumis melo L. var. makuwa

Oriental melon ( Cucumis melo L. var. makuwa ) is one of the most important cultivated cucurbits, and is grown widely in Northeast Asian countries. With increasing interest in its biological properties and economic importance, oriental melon has become an attractive model crop for studying various horticultural traits. A previous genome sequence of the melon was constructed from a homozygous double-haploid line. Thus, individual reference genomes are required to perform functional studies and further breeding applications. Here, we report draft genome sequences of two oriental melons, Chang Bougi and SW3. The assembled 344 Mb genome of Chang Bougi was obtained with scaffold N50 1.0 Mb, and 36,235 genes were annotated. The 354 Mb genome of SW3 was assembled with scaffold N50 1.6 Mb, and has 38,173 genes. These newly constructed genomes will enable studies of fruit development, disease resistance, and breeding applications in the oriental melon.
