Figure 9From: Genome-wide identification, classification and expression profiling of nicotianamine synthase (NAS) gene family in maizeScheme showing the complementary expression patterns of class I and class II maize NAS genes link to their specific physiological functions. The left panel shows the schematic diagram of putative physiological functions of ZmNASs during iron uptake and translocation of maize plant. The right panel shows the hypothetical model regulate the equilibrium between iron acquisition and homeostasis by establishing a complementary expression pattern of class I and class II maize NAS genes.Back to article page
