Evolutionary relationships of the plant Nramp family transporters. (A) An unrooted phylogenetic tree for the 25 plant metal transporters of the Nramp family was built by MEGA6. The five clades of the evolutionary tree are indicated by circles, with the OsNrat1 containing group (group III) and the OsNramp3 containing group (group IV) colored in blue and red, respectively. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. (B) Related to (A), the evolutionary tree is shown in a squarish-corner style. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches.
