Angiosperm phylogeny using ESTs for 13 shared single copy genes. The tree depicted to the left is the MP tree determined from the concatenated data matrix for 13 single copy genes using 69 seed plant taxa. The tree depicted on the right is the ML tree determined from the concatenated data matrix for 13 single copy genes using 69 seed plant taxa. Bootstrap values are indicated by the colored bars placed on branches with greater than 50% bootstrap support. Picea sitchensis was used as the outgroup taxa for all analyses. Taxa are color-coded as follows: monocots (green); euasterid I (light blue); euasterid II (dark blue); eurosid I (pink); eurosid II (red); core eudicot (purple); basal eudicot (brown); magnoliid (orange); basal angiosperm (dark gray); gymnosperms (black).
