Phylogenetic tree of the Spelt52.1 and Spelt52.2 sequences from T. aestivum and Ae. speltoides. Ae. speltoides sequences Spelt52.1 and Spelt52.2 were taken from GenBank. All Spelt52 sequences contained in T. aestivum BAC_2050O8 were represented by the consensus Spelt52_2050O8 sequence. Neighbor-joining phylogenetic tree with 500 bootstrap replicates was constructed using MEGA4 software package .
