Protein structure of PICC and PICL, and phylogenetic tree of PICC, PICL and their orthologs in vascular plants.

<p>(<b>A</b>) Putative protein structure of PICC and PICL showing coiled-coil and transmembrane domains. (<b>B</b>) Graphical representation of the maximum-likehood phylogenetic tree of PICC, PICL and their orthologs. This phylogenetic tree is based on the multiple sequence alignment shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057283#pone.0057283.s001" target="_blank">Figure S1B</a>. Branch support values are indicated at the nodes as calculated by the PhyML program using default parameters. Os, <i>Oryza sativa</i>; Pt, <i>Populus trichocarpa;</i> Rc, <i>Ricinus communis;</i> Sb, <i>Sorghum bicolor;</i> Vv, <i>Vitis vinifera.</i>
