Future Prospects of Genomics and Breeding in Bitter Gourd

Draft genome sequence of bitter gourd was currently released, but further improvements of assembly are required in its total length and number of scaffolds. Recent advances in the long-read sequencing technologies will allow to obtain the whole genome sequence of bitter gourd at chromosome level. Complete genome sequence and high-density linkage map are greatly helpful for finding genes for agronomic traits or biosynthesis of medicinal substances. Once candidate genes are found by genomic and genetic analyses, their biological functions should be elucidated. For this purpose, establishment of more efficient and easier method of genetic transformation is the future issue in bitter gourd. Genome information in bitter gourd must contribute to the study of intra- and inter-species genetic diversity in the Momordica species.
