Genetic linkage map of P. teres f. teres. Linkage groups are drawn with genetic distance in cM on the scale bar to the left and are ordered according to their genetic length. AFLP markers are indicated by the MseI (M) and EcoRI (E) primer combination (Additional file 6), followed by the size of the marker. SSR markers were developed from three sources: ESTs, STMSs and the genome assembly, prefixed PtESTSSR_, hSPT2_, and PttGS_, respectively. The mating type locus (MAT) is depicted in bold on linkage group 4.
