- ... In plants, different forms of nitrogen (NO3− or NH4+) affect nutrient uptake and environmental stress responses. In the present study, we tested whether NO3− and NH4+ affect the ability of rice (Oryza sativa) to tolerate the toxic heavy metal cadmium (Cd). Compared with NO3−, NH4+ treatment significantly increased chlorophyll contents and reduced Cd2+ levels in rice cultivars Nipponbare (japonica) ...

- ... NH4+ and NO3− are two major nitrogen sources that differentially affect the uptake and transfer of other nutrients in rice (Oryza sativa), although their effects on Fe remobilization under Fe-starvation conditions are largely unknown. Here, by investigating the rice cultivar ‘Kasalath’ (Kas), which is tolerant of nutrient-deficient soil, we found that NH4+ negatively regulates the hemicellulose 1 ...
