The origin of the btr1 allele found in domesticated einkorn wheat. (A) The eleven recognized Btr1 haplotypes found in Tm (three haplotypes)and Tb (eight haplotypes). Identical nucleotides are shown in the first line as dots. The A119T amino acid substitution caused non-brittle phenotype in Tm. (B) A phylogenetic analysis of Btr1 based on nucleotide sequence spanning the Btr1 coding sequence plus 750 bp upstream and 900 bp downstream of the coding sequence. Wheat 4X_Btr1-A and -B T. turgidum ssp. dicoccoides ‘Zavitan’ (A and B genome) formed the paraphyletic outgroup. Domesticated haplotypes are indicated by underline. Local bootstrap values after 1000 replicates are indicated near the branches.
