Nucleotide diversity values Pi (π, black line) and Theta (θ, grey line) in GAMYB using the sliding window approach (step size, 25 bp; window size, 100 bp) in H. vulgare (a) and T. aestivum B-genome (b). The structure of GAMYB is given between Fig. a and b; the open boxes show the position of the functional MYB domain
