NRT1.1-dependent NH4+ toxicity in Arabidopsis is associated with disturbed balance between NH4+ uptake and assimilation

, 2017
The nitrate transporter NRT1.1 is involved in plant NH4+ toxicity; however, its mechanism remains undefined. In this study, wild-type Arabidopsis (Col-0) and NRT1.1 mutants (chl1-1 and chl1-5) were grown hydroponically in NH4NO3 and (NH4)2SO4 media to ...

OsAMT1.1 Expression by Nitrate-Inducible Promoter of OsNAR2.1 Increases Nitrogen Use Efficiency and Rice Yield

Rice Science, 2023
Nitrate (NO3–) and ammonium (NH4+) are two main inorganic nitrogen (N) sources during crop growth. Here, we enhanced the expression of OsAMT1.1, which encodes a NH4+ transporter, using the NO3–-inducible promoter of OsNAR2.1 and an ubiquitin promoter in ...

Feedback inhibition of AMT1 NH4 +-transporters mediated by CIPK15 kinase

BMC Biology, 2020
Background Ammonium (NH4 +), a key nitrogen form, becomes toxic when it accumulates to high levels. Ammonium transporters (AMTs) are the key transporters responsible for NH4 + uptake.

Improved Productivity of Streptomyces mobaraensis Transglutaminase by Regulating Zymogen Activation

Frontiers in Bioengineering and Biotechnology, 2022
Streptomyces mobaraensis transglutaminase (TGase) is extracellularly expressed as a zymogen and then activated by TGase-activating protease (TAP). In this study, we reported the strategy for improving TGase production via the regulation of TAP activity ...

Growth, physiology, and metabolism of Halomonas meridiana in aqueous ammonium sulfate with implications for icy moon astrobiology

Frontiers in Microbiology
The discovery of extraterrestrial reservoirs of liquid water has motivated missions to icy moons Europa and Titan. Tentative evidence of ammonium sulfate ((NH4)2SO4) has been detected on the surface of Europa, and (NH4)2SO4 could be a prominent ...
