The last two decades has been the most exciting period in cucurbit genetic, genomic, and breeding research especially for cucumber, melon, and watermelon. In addition, cucumber became the first cucurbit to be sequenced, after other field crops such as rice, sorghum, soybean, and maize. In thirteen chapters by 34 internationally renowned scientists,

This book provides an overview of the current state of knowledge of the genetics and genomics of the agriculturally important Cucurbitaceae plant family, which includes crops such as watermelon, melon, cucumber, summer and winter squashes, pumpkins, and gourds. Recent years have resulted in tremendous increases in our knowledge of these species due to large scale genomic and transcriptomic studies and production of draft genomes for the four major species, Citrullus lanatus, Cucumis melo, Cucumis sativus, and Cucurbita spp. This text examines genetic resources and structural and functional genomics for each species group and across species groups. In addition, it explores genomic-informed understanding and commonalities in cucurbit biology with respect to vegetative growth, floral development and sex expression, fruit growth and development, and important fruit quality traits.

Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops.

Cucumis hystrix (2n = 2x = 24) is the only known species in the genus Cucumis that is cross-compatible with cucumber (C. sativus, 2n = 2x = 14) and has potentials for cucumber improvement. To facilitate introgression of C. hystrix chromatins into cucumber genetic background, we developed a draft genome assembly for C. hystrix (TH1 accession) which contained 16,865 scaffolds (~78x coverage) for a total of 226.0 Mb, representing ~51% of the estimated 447 Mb C. hystrix genome. Through genotyping-by-sequencing (GBS), a linkage map for C. hystrix was constructed with 1,692 SNP loci, which was then integrated with a previously developed genetic map with 410 SSR markers. The resulting consensus map consisted of 12 linkage groups spanning 1119 cM and anchor 1,321 scaffolds, accounting for 60.2 Mb or ~26.62% of C. hystrix draft genome assembly. A karyotype for the C. hystrix genome was developed with molecular cytogenetic landmarks which allowed for a better understanding of the syntenic relationships among C. hystrix, cucumber and melon (C. melo, 2n = 2x = 24) chromosomes as well as the mechanisms in which the seven cucumber chromosomes were evolved from an x=12 ancestor through dysploid chromosome reduction. C. hystrix introgression lines (IL) in elite cucumber backgrounds were developed through marker-assisted backcrossing. Overall, 334 ILs were identified by SSR markers to carry C. hystrix alleles. These ILs included different introgression segments that covered about 57.29% of C. hystrix map. With genotyping-by-sequencing (GBS), the introgressions in the 55 ILs included 44 syntenic blocks or about 74.57% coverage of C. hystrix genetic map. Each IL has an average 5.4 introgression segments, averaging 1.7 Mbp in size. Homoeologous recombination reduction was observed genome-wide but recombination hotspots in C. hystrix were also identified. Phenotypic characterization for resistance to angular leaf spot (ALS) and downy mildew (DM) pathogens was conducted in selected ILs. Both genotypic data and phenotypic data indicated that the intermediate resistance to ALS in nine ILs and the high resistance to DM in four ILs was of C. hystrix origin. These C. hystrix introgression lines, although time consuming in development, should be valuable resources for cucumber improvement.
