Figure 2From: Genome-wide identification, classification and expression profiling of nicotianamine synthase (NAS) gene family in maizeThe multiple sequence alignment of maize NAS members with AtNAS1 from Arabidopsis thaliana and OsNAS1 from rice. The first and second NAS region in ZmNAS2;1 (ZmNAS2;2) were designed as ZmNAS2;1–1 (ZmNAS2;2–1) and ZmNAS2;1–2 (ZmNAS2;2–2), respectively. The light or dark shaded backgrounds indicate partial or entire conservative residues.Back to article page
