Fifty percent maximum likelihood majority-rule bootstrap consensus summary tree of Viridiplantae inferred from the amino acid (AA) analysis. Data set derived from 78 protein-coding genes of the plastid genome (ntax = 360; 19,449 AAs; missing data ~15.6%). Bootstrap support values ≥ 50% are indicated. Terminals with a triangle represent collapsed clades with > 2 taxa. See Additional file 6 for the complete tree and Additional file 1 for taxonomy. Lami. = Lamiidae; Campanuli. = Campanulidae.
