Fig 4. Neighbor-joining tree of the 23 newly identified α-gliadin genes (solid circle) in T. urartu accession PI428198 and additional α-gliadin genes from Triticum and Aegilops species.

The prefix abbreviations and geometric figures of GenBank accession numbers indicate the different genomes. As: Ae. speltoides; At: Ae. tauchii; Ta: T. aestivum; Tdi: T. dicoccoides; Tdu: T. durum; Tm: T. monococcum. A: A genome; B: B genome; D: D genome. The suffix letters of each accession number, a and p, respresent active and pseudo- genes, respectively.
