From: Homoeologous duplicated regions are involved in quantitative resistance of Brassica napus to stem canker

Figure 4

Distribution of resistance-associated markers located in strictly duplicated regions of the B. napus genome. The coloured segments correspond to the six duplicated blocks, as defined by Schranz et al. [17], on which associated markers were identified in regions collinear to the same A. thaliana sequence interval. All the known duplications of these six blocks in the B. napus genome are shown. The number of resistance-associated markers identified on each block is indicated in parenthesis. The absence of a number indicates that no association was identified in the region. The resistance QTL identified in bi-parental or connected populations by linkage mapping on the copies of the 6 duplicated blocks are represented by stars on the right of the linkage groups. Orange stars indicate co-localisation of associated markers and previously identified QTL, black stars indicate loci where QTL were detected but where no resistance associated marker was identified. Linkage groups are organized according to the colinearity between the A and C genomes. The orientation of the arrows indicates the orientation of the colinearity between the genomic regions.
