The origin of the Btr2 allele found in domesticated einkorn wheat. (A) The 16distinct Btr2 haplotypes found in Tm (three haplotypes) and Tb (14 haplotypes), of which one (B2_Hap14) is represented in both genepools. Identical nucleotides are shown in the first line as dots. (B) A phylogenetic analysis of Btr2 based on nucleotide sequence spanning the Btr2 coding sequence plus 350 bp upstream and 650 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. Cultivated haplotypes are indicated by underline. Local bootstrap values after 1000 replicates are indicated near the branches.
