- ... High nitrogen (N) application improves the acclimation of plant photosynthesis to water deficit stress, however, the metabolic details for this are not yet fully understood. Using hydroponics, we found that moderate water deficit simulated with 10% PEG 6000 inhibited rice photosynthetic rate by 17.2% in low N condition (LN, 0.71 mM) versus 7.9% in moderate N condition (MN, 2.86 mM). Plants grown a ...

- ... 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 ...
