Phylogenetic tree of soybean, Arabidopsis, rice and Medicago plant Pi transporter proteins in Pht1 family.

<p>Transporters and corresponding plant species are as follows: rice (<i>Oryza sativa</i>), OsPT1 through OsPT13 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0047726#pone.0047726-Paszkowski1" target="_blank">[16]</a>; Arabidopsis (<i>Arabidopsis thaliana</i>), AtPht1;1 through AtPht1;9 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0047726#pone.0047726-Mudge1" target="_blank">[14]</a>; Medicago (<i>Medicago truncatula</i>) MtPT1 through MtPT6 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0047726#pone.0047726-Grunwald1" target="_blank">[68]</a> and other four PT proteins obtained in Phytozome (<a href="http://www.phytozome.net/medicago" target="_blank">http://www.phytozome.net/medicago</a>), soybean (<i>Glycine Max</i>), GmPT1 through GmPT14 (this work).
