Phylogenetic analysis of MAPs.

<p>A phylogenetic tree was generated with the neighbor-joining method using the p-distance in MEGA version 5.04 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0058681#pone.0058681-Tamura1" target="_blank">[47]</a> from all complete MAP protein sequences of <i>Arabidopsis</i> and poplar. Branch lengths are proportional to the amino acid distances along each branch. The neighbor-joining bootstrap values for clusters supported above the 50% level are indicated in the red font above the branches, whereas minimum-evolution bootstrap values above the 50% level are presented in red font below the branches. The blue diamonds are highlighted at the front of all MAPs from <i>Populus</i>. PtrMAP1A (XP_002320050.1); Ptr MAP1B (XP_002311439.1); Ptr MAP1C (JGI protein ID, 225648); Ptr MAP1D (XP_002306464.1); Ptr MAP1E (XP_002336218.1); Ptr MAP2A (XP_002301676.1); Ptr MAP2B (XP_002305888.1); Ath MAP1A (AAP37849.1); Ath MAP1B (AEE28993.1); Ath MAP1C (AEE77063.1); Ath MAP1D (AEE86740.1); Ath MAP2B (AEE79999.1); Ath MAP2A (AAP21284.1).
