Phylogenetic analysis of GmNRP–like genes. The amino acid sequences of NRP-like proteins were recovered from TAIR (http://arabidopsis.org/) and Phytozome v10.3 databases and aligned using MUSCLE. Phylogenetic trees were constructed using Bayesian inference performed with MrBayes v3.2.2 with mixed amino acid substitution model (Blosum). The analyses were carried out running 20.000.000 generations and excluding the first 5.000.000 generations as burn–in. GmNRPs from soybean is depicted in blue and from Arabidopsis in red. Background colors demark clusters and sub–clusters formed by NRP homologs. The three–letter abbreviation in parenthesis preceding the nomenclature of the NRP homologs denotes the plant species, such as Ath: Arabidopsis thaliana, Cpa: Carica papaya, Csi: Citrus sinensis, Csa: Cucumis sativis, Gma: Glycine max, Mes: Manihot esculenta, Pvu: Phaseolus vulgaris, Sly: Solanum lycopersicum, Stu: Solanum tuberosum, Tae: Triticum aestivum, Osa: Oryza sativa and Zma: Zea mays
