Molecular marker linkage map of the Nicotiana langsdorffii genome. The 12 linkage groups (LGs 1–9 plus LG-A, -B, and -C) together comprise a recombinational length of 1062 cM. The vast majority of the markers were present in only one of the two parental inbred lines used in the segregation studies. Loci indicated in red originated in S-4-1 (susceptible to P. tabacina), while those in blue came from S-4-4 (resistant to P. tabacina). Markers with alleles present in both S-4-1 and S-4-4 are shown in black. The R-gene locus, NlRPT, is shown in green. Locus names in the three segregation distortion regions (SDRs) on LGs 1, 5, and 9 are shown in boldface. Locus nomenclature: AFLPs – primer combination followed by fragment size in bases (e.g., ExxMxx_123); SSRs – locus names begin with A, B, C, D, GIS, or KTRDC; COSII – AtXg followed by a five digit number; ISSR loci – U825 or U826 followed by the fragment in bases; ISSR/SCAR – cloned fragment size indicated as a four digit number, followed by the size of the scored fragment if different (e.g., U826_1900/700); TRAP loci – gene-specific primer+random primer followed by the fragment size in bases (e.g., NBS9+em3_117).
