Phylogenetic Trees from Analysis of Combined 18S and 26S rDNA data (Buchheim et al. [2001]):

MP analysis I: One tree of three, equally parsimonious solutions (L = 5925, CI [Kluge and Farris 1969] = 0.35, RI [Farris 1989] = 0.59, RC [Farris 1989] = 0.24) from MP analysis of combined sequence data. Nodes that collapse in a strict consensus analysis are denoted by an asterisk. Nodes that differ in ML analyses of the same data are denoted by a "#" and nodes that differ in ME analyses of the same data are denoted by a "†."

SRC analysis: Optimal tree (p = 0.53) from analysis of combined sequence by substitution rate calibration.

MP analysis II: Results from combined analysis II of 18S and 26S rDNA sequence data in which putative "long-branch" lineages were removed prior to analysis. One tree of four, equally parsimonious solutions (L = 4237, CI [Kluge and Farris 1969] = 0.47, RI [Farris 1989] = 0.60, RC [Farris 1989] = 0.29) from MP analysis. Branch lengths are drawn proportional to estimates of evolution along branches (see scale in upper left). Nodes that collapse in a strict consensus analysis are denoted by an asterisk. Nodes that differ in ME and ML analyses of the same data are denoted by a "#". Bootstrap values as percentages from ME, ML and MP analysis are presented (stacked one on top of the other) at each internode. Nodes without bootstrap values were supported in fewer than 50% of all replicates. Brackets identify orders of chlorophycean green algae represented in the analyses.
