Phylogenetic positions of Chlorokybus and Mesostigma within the Viridiplantae as inferred from structural features of the chloroplast genome. (A) MP analysis based on gene content. The strict consensus of 12 equally parsimonious trees is shown. (B) MP analysis based on gene order. The strict consensus of 56 equally parsimonious trees is shown. The nodes that received 100% bootstrap support are denoted by asterisks. For the other nodes, only the bootstrap values ≥50% are indicated.
