  1. For each duplicated regions on which resistance-associated markers (RAM) were identified, information is provided about the number and proportion (in parentheses) of resistance-associated markers, the size of the intervals with RAM, the marker density and the linkage disequilibrium in the interval. The correspondence of resistance-associated markers with A. thaliana gene intervals is also shown. The co-localisation of resistance-associated markers with previously identified QTL (in a double haploid and/or a connected population also from our laboratory) is indicated.
