Mtr.11959.1 is a regulatory B′ subunit of the Ser/Thr phosphatase type 2A family. The unrooted phylogenetic tree was calculated from the alignment presented in Supplemental Figure S4, including the amino acid sequences from the B, B′, and B′′ regulatory subunits of the Ser/Thr phosphatases type 2A of Arabidopsis (At.), rice (Os.), and M. truncatula (Mt.). Branch labels indicate bootstrap values (n = 1,000) of the consensus tree. Low bootstrap values are not shown. Labels at the branch tips include unique identifiers (GenBank/Uniprot) followed by the species designation; for Mtr.11959.1, the GenBank identifier is KC859637.
