Nucleotide diversity θ
of individual A-genome genes. Gene diversity along the A-genome chromosomes in T. aestivum and wild emmer (T. dicoccoides) in the Diyarbakir region in Turkey. Chromosome 4A is excluded because the order of genes does not conform to the Ae. tauschii genetic map. Monomorphic loci are depicted with zero diversity. The gene order along the diversity maps in Additional file 2 Table S1 is used on the X-axis, and the maps are oriented with the most distal gene in the short arm to the left. Centromere is indicated by a triangle. Genetic distances between genes are not depicted.
