Phylogenies supported by shared sequence characteristics. A: Maximum likelihood trees inferring a heterokont origin of RuBisCO small subunit and phosphoribulokinase in L. chlorophorum. B: Alignment of the genes demonstrating shared sequence characteristics between L. chlorophorum and streptophytes and heterokonts, respectively. Filled dots indicate 100% bootstrap support. Bayesian posterior probability values are indicated for some of the most important splits.
