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 haplotypes 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.
