BMC Genomics 2006, 7:12 http://www.biomedcentral.com/1471-2164/7/12 FHiagpulorteyp6es at the VvF3'5'H-1 and VvF3'5'H-2 loci Haplotypes at the VvF3'5'H-1 and VvF3'5'H-2 loci. SSCP haplotypes at the VvF3'5'H-1 locus and length polymorphic haplo- types at the VvF3'5'H-2 locus were identified in the BAC clones positive for the presence of flavonoid 3',5'-hydroxylase genes on contigs ctg313, ctg871, ctg1320 and ctg2373 (above). Names written in horizontal refer to BAC clones and contigs; those written in vertical refer to gene copies of flavonoid 3',5'-hydroxylases. The relation between the symbol (■ ● ❍ ) used in the picture and the corresponding haplotype displayed in a representative BAC clone is shown below. The symbol 'X' stands for lack of the presence of a given haplotype in the corresponding BAC clone. BES17K04-FM inherited from 'Cabernet Sauvignon', which corresponded to the SSCP band amplified from the BAC clone 17K04, was amplified in the mapping popula- tion and completely co-segregated with SSR VrZag30 and BES9C17-FM. The marker BES38C24-RM mapped 2.2 cM apart from those three markers and co-segregated with SSR VMC3a8. All contigs ctg313, ctg871, ctg1320 and ctg2373 were located on LG6 in the region covered by the markers VrZag30, VMC3a8, BES9C17-FM, BES17K4-FM and BES38C24-RM. This interval spanned 2.2 cM in the 'Cabernet Sauvignon' parental map. Contigs ctg313, ctg871, ctg1320 were also cross-referenced to the V. vinif- Page 9 of 17 (page number not for citation purposes)
