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

Figure 3

Quantitative determination of amino acid polymorphism in the NTT domain of αCENH3, leading to nonsynonymous amino acid substitutions. On the x-axis, the position in the amino acid sequence; on the y-axis, the percentage of clones having substitutions in polymorphic positions to the total number of clones sequenced. (a) Parental forms: Verasen’ and Mikhas’; hybrids: Verasen’ × Mikhas’. (b) Parental forms: Verasen’ and Dubrava; hybrids: Verasen’ × Dubrava. Note: fifteen cDNA clones were sequenced for each parental plant and the deduced amino acid sequences were obtained. About 40-45 clones were sequenced for each hybrid plant.
