Neighbor-joining tree of Ets DNA binding domain amino acid sequences of vertebrate PU.1 family transcription factors. This tree was constructed by using the me tree program, using proportions of differences as a distance measure and excluding gaps. This method finds a phylogenetic tree and statistically similar trees likely to represent a minimum total genetic difference (branch length) among the genes. The value at each node represents the probability that that branch length is not zero.
