Figure 2. Maximum-likelihood tree inferred form the Pgk1 sequence of Kengyila and its affinitive species within Triticeae.

Numbers with bold above nodes are Bayesian posterior probability values ≥90% numbers below nodes are bootstrap values ≥50%. The numbers after species names refer to the distinct homoeologous copy of the Pgk1 gene. The capital letters in bracket indicate the genome type of the species. Different color labeled the geographic information of Kengyilia species and its affinitive donors.
