Dynamics of the Centromeric Histone CENH3 Structure in Rye-Wheat Amphidiploids (Secalotriticum)

Figure 2

The amino acid consensus sequences of αCENH3 NTT domain derived from parental forms of rye (Verasen’), triticale (Mikhas’, Dubrava), and secalotriticum amphidiploids (STr VM and STr VD). The asterisks indicate the positions of nonsynonymous amino acid substitutions. Amino acid polymorphic positions are color-coded according to their frequency: white, if below 50%; light-gray, if above 50%. In the positions 41, 54, 56, and 66, the percentage of substitutions does not exceed 50%, although it has high values for Dubrava and the hybrid; therefore the amino acids with the highest percentage are shown in these positions. The exact quantification of amino acid substitutions in the polymorphic positions is provided in Figure 3.
