Genes involved in nitrogen use efficiency processes have been identified in the previous studies, however, only a small number of these genes have been found to improve grain yield by promoting tillering. Heterogeneity in rice tillers yield is increased with increasing N rates. Since elevated expression of OsNPF7.2 is capable of improving rice grain yield, this gene might be applied to high-yield rice breeding. Our results suggested that OsNPF7.2 is a positive regulator of nitrate influx and concentration, and that it also regulates cell division in tiller bud and alters expression of genes involved in cytokinin and strigolactone pathways, resulting in the control over rice tiller number. Tiller number and spikelet fertility (seed set) are two critical traits that define grain yield in rice. [2]. doi: 10.1007/s00299-008-0665-z.
