Fig. 2. Comparative analysis of the deduced amino acid sequences of Puroindoline-a, -b and Grain Softness Protein-1 from Ae. tauschii and the wild-type ‘a’ alleles of T. aestivum. A dot (.) shows identity with the first sequence. Underlined amino acids indicate synonymous substitutions relative to the wild-type. Double underlined amino acids indicate synonymous and nonsynonymous substitutions.
