A grapevine (Vitis vinifera L.) genetic map integrating the position of 139 expressed genes.

摘要: Grapevine molecular maps based on microsatellites, AFLP and RAPD markers are now available. SSRs essential to allow cross-talks between maps, thus upgrading any growing grapevine maps. In this work, single nucleotide polymorphisms (SNPs) were developed from coding sequences unique BAC-end sequences, nested in a SSR framework map of grapevine. Genes participating flavonoids metabolism defence, signal transduction pathways related genes also considered. Primer pairs for 351 loci ESTs present public databases screened polymorphism the “Merzling” (a complex genotype Freiburg 993–60 derived multiple crosses involving wild Vitis species) × Vitis vinifera (cv. Teroldego) cross population. total 138 SNPs, 108 phenotypic trait (berry colour) mapped 19 major linkage groups consensus map. specific cases, with putatively functions near QTLs previously identified resistance berry ripening. anthocyanin different groups. A myb gene, which has been correlated biosynthesis, cosegregated colour group 2. The possibility associating candidate known position QTL is discussed plant.
