Vinod KK, Heuer S (2012). Approaches towards nitrogen- and phosphorus-efficient rice. AoB PLANTS 2012: pls028; (DOI:10.1093/aobpla/pls028).

For thedevelopment of nutrient-efficient rice,a holistic approach should be followed combining optimized fertilizer management with enhanced nutrient uptake via a vigorous root system, leading to increased grain filling and yield. Despite an increasing number of N- and P-related genes and QTLs being reported, very feware actively used inmolecular breeding programmes. The complex regulation of N- and P-related pathways challenges breeders and the research community to identify large-effect genes/QTLs. For this it will be important to focus more on the analysis of tolerant genotypes rather than model plants, since tolerance pathways may employ a different set of genes.
