A comparison of each NRAMP transporter's 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 a characterized ferrous iron transporter of the NRAMP family, AtNRAMP3, was calculated by a clustalW alignment.
