A phylogenetic tree of BCAT proteins in plants constructed using the neighbour-joining method. BCATs group into plastidial (orange line) and mitochondrial (blue line) clades, with apparent division into dicot and monocot subclades. A third clade (grey line) includes BCATs that fall into neither group. BCATs with experimentally-confirmed organelle localization are labelled: P, plastid; M, mitochondrion; C, cytosol. Species abbreviations are found in Methods (At, Arabidopsis thaliana; Hl, Humulus lupulus; Sl, Solanum lycopersicon). *As we note in the Discussion, the plastid localization of AtBCAT2 requires further analysis.
