A comparison of each ZIP transporters expression in root and nodule tissue from two soybean transcriptome studies is presented (Libault etal., 2010; Severin etal., 2010). A prediction of the number of transmembrane domains (TMD) for each protein was analyzed using SOSUI (http://bp.nuap.nagoya-u.ac.jp/sosui/sosui_submit.html). Homology to characterized ferrous iron transporters of the ZIP family, MtZIP6 and AtIRT1 was calculated by a clustalW alignment.
