The molecular connection between nitrogen utilization efficiency (NUE) and biomass production is unclear. Here, the authors show that differences in NUE and cellulose biogenesis between rice indica and japonica subspecies can be explained by variation at the MYB61 locus, which is regulated by the NUE regulator GRF4.
