Genetic map locations of AFLP anchored BACs of the potato AFLP physical map. The genetic map of parent RH has twelve chromosomes (RH01 to RH012) and is made up from AFLP markers of the enzyme combinations EcoRI/MseI, SacI/MseI and PstI/MseI. Per chromosome, the genetic map is divided into up to 105 numbered bin segments that each represent a distance of one crossover event (0.77 cM) in the mapping population. The number of RH AFLP markers placed in each bin is indicated by a grey intensity value. Red bars indicate the counts per bin of BACs that are anchored to the genetic map by an EcoRI/MseI AFLP marker in their contig. For AFLP markers that mapped to a range of bins, the associated BAC counts have been evenly distributed over these bins. The bins with the centromere have their BAC count shown in blue and follow the identifications by Tang et al. [31] and Park et al. [42]. The BACs of the Nucleolar Organizer Region (NOR) do not have an AFLP anchor, but were identified by their end sequence. Chromosome orientations are according to bin number in the ultradense genetic map. For alignment to other potato and tomato genetic maps, e.g. from Tanksley et al. [43], chromosomes 7, 10 and 12 are in the wrong orientation and must be inverted.
