An example of synteny between cultivated peanut, the A-genome Arachis map and Medicago. Synteny between a linkage group from cultivated peanut (fAhIII, meaning AhIII "flipped"), an A-genome linkage group (Ar3) developed here and two chromosomes of Medicago (Mt4 and Mt7). Synteny of the cultivated linkage group to Medicago can be inferred by using the A-genome map as a bridge, in addition the position of candidate genes on the map of cultivated peanut can be inferred. Marker names in Medicago are BAC clone identification codes. Genetic distances in Arachis are in cM, and in Medicago in Mbp of DNA. Candidate genes are highlighted in bold and red.
