Phylogenetic analysis of the RuBisCO large subunit (CbbL). Representative amino acid sequences were obtained from GenBank. Bootstrap values (1,000 replicates) are shown at the branches. The bar represents 20% sequence divergence. The neighbor-joining tree is drawn to scale; the evolutionary distances were computed using the Dayhoff matrix-based method, and units are the numbers of amino acid substitutions per site. All positions containing alignment gaps and missing data were eliminated only in pairwise sequence comparisons (pairwise deletion option). There were a total of 539 positions in the final data set.
