The availability of nitrogen in the soil is one of the main limiting factors for plant
productivity, biomass accumulation and crop yield. Well-aerated soils are relatively rich
in N03- and poor in NH4 +, whereas in anaerobic soils of irrigated or rain-fed lowland rice,
NH4 + is the most prevalent source of nitrogen. Ammonium uptake is presumed to be
controlled by at least two gene families in plants, namely AMTJ and AMT2. Each gene
family consists of one to several members, some of which...[Show more]
