Phylogeny of ABCB genes from land plants, based upon coding sequences from the loci listed in Table A4, analyzed using dynamic homology under the parsimony criterion. Gray branches indicate nodes with bootstrap support lower than 50%. Algal ABCBs are colored light blue–green, basal land plants blue, Populus green, Arabidopsis red, and monocots yellow. Abbreviated names of each species are listed in Table A1.
