2011 Gene list for melon

Résumé

Melon (Cucumis melo L.) is an economically important, cross-pollinated species. Melon has 2n = 24 chromosomes and a relatively small genome (450 Mb), about three times larger than the Arabidopsis thaliana genome and similar to the rice genome (Arumanagathan and Earle, 1991). Melon has high intra-specific genetic variation and morphologic diversity. A great variety of genetic and molecular studies have been conducted on important agronomical traits, such as resistance to pathogens and insects, and floral and fruit traits. The following list is the latest version of the gene list for melon. Previous gene lists were organized by Pitrat: (Pitrat, 2006), (Pitrat, 2002), (Pitrat, 1998), (Pitrat, 1994), (Pitrat, 1990), (Pitrat, 1986), (Committee, 1982). This current list has been modified from previous lists in that (1) it provides an update of the known genes and QTLs, and (2) it adds an expanded description for reported genes including sources of resistance and resistance genes, phenotypes of mutants and traits related to seeds, seedlings, plant morphology and architecture, flowers and fruits. Locations of the reported genes on the melon genetic map and linked markers useful for marker assisted selection were reported where available. Since the first molecular marker-based melon map published in 1996 (Baudracco-Arnas and Pitrat, 1996), several genetic maps of melon have been published by several research teams, using several segregating populations. 2011 will be the year of the publication of an integrated map of melon in the framework of the International Cucurbit Genomic Initiative (Díaz et al., 2011). The integrated map has been constructed by merging data from eight independent mapping populations using genetically diverse parental lines. It spans 1150 cM distributed across the 12 melon linkage groups and comprises more than 1500 markers. Individual maps and the integrated map are available at www.icugi.org. The linkage groups were named according to Perin et al., 2002. The same nomenclature will be adopted hereafter. QTLs for 62 traits including virus resistance, fruit shape, fruit weight, sugar content have been located on this integrated map (Díaz et al., 2011). The list of melon sequences was not updated, as melon ESTs and full cDNAs are increasing extraordinarily (www.icugi.org). A physical map of the melon genome, anchored to the genetic map, has been established (Gonzalez et al., 2010) and the complete melon genome sequence is expected by the end of the year.
