Light-Independent Nitrogen Assimilation in Plant Leaves: Nitrate Incorporation into Glutamine, Glutamate, Aspartate, and Asparagine Traced by 15N

open access: yesPlants, 2020
Although the nitrate assimilation into amino acids in photosynthetic leaf tissues is active under the light, the studies during 1950s and 1970s in the dark nitrate assimilation provided fragmental and variable activities, and the mechanism of reductant ...

Nitrogen assimilation in orchids [PDF]

open access: yesHortScience, 1992
The uptake of nitrate and ammonium by a terrestial (Bromheadia finlaysonia) and an epiphytic (Dendrobium hybrid) orchid in solution culture has been studied. The rates of nitrate and ammonium were relatively linear, with higher rate of uptake for ammonium. The rates of nitrate uptake in terrestial and epiphytic orchids were 0.4 and

Assimilation of nitric oxide by Heterosigma akashiwo in the presence of other nitrogen sources

open access: yes, 2021
Coyne, Kathryn J.Heterosigma akashiwo is a globally distributed harmful algal bloom species which can use nitric oxide (NO), a toxic free radical produced in anoxic sediments, as their sole nitrogen source. Heterosigma akashiwo possesses a hybrid nitrate

Overexpression of IbSnRK1 enhances nitrogen uptake and carbon assimilation in transgenic sweetpotato

open access: yesJournal of Integrative Agriculture, 2018
Nitrogen is an important nutrient for plant development. Nitrogen and carbon metabolisms are tightly linked to physiological functions in plants. In this study, we found that the IbSnRK1 gene was induced by Ca(NO3)2.
