Comparative map of six Lx regions from soybean and Medicago. In silico genetic mapping with SSR markers placed the soybean Lx regions into four different linkage groups (LGs). Two BAC clones, gmw1-9c4 and gmw1-91g6, were selected containing Lx1, Lx2 and Lx3, and these genes were embedded in Scaffolds 88 and 134. Two blocks showing synteny with selected BACs were detected in Medicago and contig 148 on Medicago chromosome 2 was more similar to the BACs. Blast search with the sequence of contig 214 on Medicago chromosome 8 resulted in two more soybean Lx scaffolds. Soybean QTLs for each Lx region are denoted as brown characters and some of them are conserved among the four regions.
