Figure 4: Phylogenetic trees of M. notabilis and other plants.
From: Draft genome sequence of the mulberry tree Morus notabilis

Different data set were used to construct a phylogeny of the considered species. (a) A tree constructed using 136 single genes in the predicted M. notabilis gene data sets and their best-matched ones. (b) A tree constructed using 62 single genes predicted by Genewise in 10 plants. (c) A tree constructed using 318 best-matched collinear genes across 6 plant genomes. The scale of a unit is shown below each tree and the number on it shows how many amino acid substitutions per sites.
