Model for the role of OsNAR2.1, OsNIT1, and OsNIT2 in mediating root growth in rice. Interaction of OsNAR2.1 with OsNRT2.1, OsNRT2.2, and OsNRT2.3a, and their effect on root nitrate uptake, were previously reported in Feng et al. (2011), Yan et al. (2011), and Liu et al. (2014). All other noted functions are demonstrated in this study.
