Fig. 3.

Distribution of ABC, NLR and START genes and SNP markers for leaf rust resistance in the A, B and D genomes of the hexaploid wheat genome. The circles were arranged according to the size of each family: inner, middle and outer circles for START, ABC and NLR genes. a: seedling A genome; b: adult A genome; c: seedling B genome d: adult B genome; e: seedling D genome; f: adult D genome. Red △ denotes markers within a gene; Blue □ denotes markers 5 Kb upstream (from the transcription start site or TSS) or downstream (from the transcription termination site or TTS) of a gene. Seven SNPs overlapped because of their close physical proximity on the same chromosome, see Additional file 5 for details. We do not show designated leaf rust (Lr) genes on the chromosome maps for seedling resistance and adult plant resistance, which are listed as follows: 1A: Lr59; 2A: Lr11, Lr17a, Lr17b, Lr37, Lr38, Lr45, Lr49; 3A: Lr63; 4A: Lr28; 5A: -; 6A: Lr56, Lr62, Lr64; 7A: Lr20, Lr47; 1B: Lr33, Lr44, Lr46, Lr51, Lr55; 2B: Lr13, Lr16, Lr23, Lr35, Lr50, Lr58; 3B: Lr27; 4B: Lr12, Lr25, Lr30, Lr31, Lr48; 5B: Lr18, Lr52; 6B: Lr3a, Lr3bg, Lr3ka, Lr9, Lr36, Lr53, Lr61; 7B: Lr14a, Lr14b; 1D: Lr21, Lr42, Lr60; 2D: Lr2a, Lr2b, Lr2c, Lr15, Lr22a, Lr22b, Lr39, Lr54; 3D: Lr24, Lr32; 4D: -; 5D: Lr1, Lr57; 6D: -; 7D: Lr19, Lr29, Lr34
