Fig. 2From: Genome-wide systematic characterization of the NRT2 gene family and its expression profile in wheat (Triticum aestivum L.) during plant growth and in response to nitrate deficiencyPhylogenetic tree of the NRT2 genes family. Phylogenetic tree of NRT2 members in higher plants was generated by protein sequence alignment with MEGA 6.0 using the neighbor-joining method, displayed by Evolview 2.0. All NRT2 proteins were assigned into three groups as clade1, 2 and 3 (indicated by red, green and blue, respectively). At: A. thaliana, Os: O. sativa, Zm: Z. mays, Ta: T. aestivum (marked by a light green, blue, yellow and pink circle, respectively)Back to article page
