From: The Litsea genome and the evolution of the laurel family
a Phylogenetic trees based on the concatenated (left) and multi-species coalescent (MSC) methods (right) using nucleotide sequences. Magnoliids are indicated with a gray background. Red stars with labels I, II, III, and IV refer to the discussions on phylogenetic discordances (see text). b Estimated proportions of the 160 single-copy gene trees with different topologies based on nucleotide alignments. The x-axis labels q1, q2, and q3 refer to the quartet support for the main topology (red), the first alternative (blue), and the second alternative (yellow), respectively. The dashed line refers to a proportion of 0.33. c Phylogenetic trees based on the concatenated (left) and MSC methods (right) using amino acid sequences. Interpretation is as in a. d Estimated proportions of the 160 single-copy gene trees based on amino acid sequences. Interpretation is same as b. Source data underlying (a) and (c) are provided as a Source Data file.
