Phylogenetic tree of synurophyte plastids. This tree was constructed using a dataset of 91 concatenated proteins (18,250 amino acids). The numbers on each node represent ultrafast bootstrap approximation (UFBoot) values (left) calculated using IQ-Tree and posterior probabilities (right). The bold branch indicates strong sipported values (ML = 100 / PP = 1.00). The scale bar indicates the number of substitutions/site
