Figure 1From: Genome-wide identification, classification and expression profiling of nicotianamine synthase (NAS) gene family in maizeNeighbor-joining phylogenetic tree of the NAS members. The tree was constructed with the amino acid sequences of NAS proteins from Maize (Zm), Barley (Hv), Rice (Os), Arabidopsis thaliana (At) and Solanum lycopersicum (chlN) using the neighbor-joining method in MEGA 4.0 software. For proteins and accession numbers used in phylogenetic analysis, refer to “Methods”. The scale bar corresponds to a distance of 5 changes per 100 amino acid positions.Back to article page
