AbstractCucumber, Cucumis sativus L. (2n = 2x = 14), is an important vegetable crop worldwide. It was the first specialty crop with a publicly available draft genome. Its relatively small, diploid genome, short life cycle, and self-compatible mating system offers advantages for genetic studies. In recent years, significant progress has been made in molecular mapping, and identification of genes and QTL responsible for key phenotypic traits, but a systematic review of the work is lacking. Here, we conducted an extensive literature review on mutants, genes and QTL that have been molecularly mapped or characterized in cucumber. We documented 81 simply inherited trait genes or major-effect QTL that have been cloned or fine mapped. For each gene, detailed information was compiled including chromosome locations, allelic variants and associated polymorphisms, predicted functions, and diagnostic markers that could be used for marker-assisted selection in cucumber breeding. We also documented 322 QTL for 42 quantitative traits, including 109 for disease resistances against seven pathogens. By alignment of these QTL on the latest version of cucumber draft genomes, consensus QTL across multiple studies were inferred, which provided insights into heritable correlations among different traits. Through collaborative efforts among public and private cucumber researchers, we identified 130 quantitative traits and developed a set of recommendations for QTL nomenclature in cucumber. This is the first attempt to systematically summarize, analyze and inventory cucumber mutants, cloned or mapped genes and QTL, which should be a useful resource for the cucurbit research community.

ABSTRACT Dosage studies and the inheritance pattern of the gene for steroid sulfatase (Sts) in the mouse have previously provided indirect evidence for a functional Y-linked allele which recombines obligatorily with its X-linked allele in male meiosis. In this study, we have investigated the linkage relationship of Sts and the sex-reversed mutation (Sxr), a gene which is known to reside in the pairing region of the Y chromosome. The results clearly demonstrate that Sxr and Sts are linked in a region of obligatory recombination and Sts maps proximal to Sxr with most recombinants occurring proximal to the two genes.

A radiation-induced mutation of cucumber (Cucumis sativus L.) which affects plant pubescence is controlled by a single recessive gene. Mutant seedlings have glabrous hynocotyls, and mature plants have glabrous internodes and leaf petioles. The laminae, especially of the first true leaf, the node areas and the perianths are slightly pubescent (glabrate). This new gene is designated glb, glabrate. There was no evidence of linkage between this gene and glabrous (gl), non-bitter cotyledon (bi), light sensitive (ls), yellow cotyledon (yc) or crinkled-leaf (cr).A sister line of glb also segregated for a lethal mutation. Mutant seedlings had pale green, slightly smaller cotyledons, and died 6 to 7 days after emergence. The mutation was controlled by a single recessive gene, designated pl, pale lethal. The gene was not linked with either glabrate (gib) or non-bitter cotyledon (bi).
