Figure 1. Soybean composite genetic map in the region of the Mi resistance quantitative trait loci on linkage group (LG)-G (a) and LG-O (b) (http://soybase.org; verified 16 April 2007). The bacterial artificial chromosome (BAC) clones were positive clones for the SSR markers. The BAC clones prefixed with "IS" (Iowa State University) or "UM" (University of Minnesota) were from the ‘Williams 82’ and ‘Faribault’ BAC libraries, respectively.
