Fig. 1 From:通用电气nome-wide identification and analysis of high-affinity nitrate transporter 2 (NRT2) family genes in rapeseed (Brassica napusL.) and their responses to various stresses Phylogenetic relationships of NRT2 family proteins in diverse species. A total of 114 protein sequences were subjected to multiple sequence alignment in ClustalW prior to constructing a phylogenetic tree using the Neighbor-Joining method in MEGA 6.06. Different groups are labeled by different colors. The aligned NRT2 proteins originating fromA.thaliana,B.napusandO.sativaare marked by triangles, circles and squares, respectively Back to article page
