Interactions between nitrate and ammonium in their uptake, allocation, assimilation, and signaling in plants.
TL;DR: Interactions between nitrate and ammonium are summarized with respect to uptake, allocation, assimilation, and signaling to help identify targets with the potential to improve crop productivity.
Nitrate Addition Alleviates Ammonium Toxicity Without Lessening Ammonium Accumulation, Organic Acid Depletion and Inorganic Cation Depletion in Arabidopsis thaliana Shoots
Takushi Hachiya,Chihiro Watanabe,Masaru Fujimoto,Toshiki Ishikawa,Kentaro Takahara,Maki Kawai-Yamada,Hirofumi Uchimiya,Yukifumi Uesono,Ichiro Terashima,Ko Noguchi +9 more
TL;DR: Analysis of growth, inorganic N and cation content and various primary metabolites in shoots of Arabidopsis thaliana seedlings grown on media containing various concentrations of nitrate and/or ammonium suggests that nitrate-dependent alleviation of ammonium toxicity is related to physiological processes that are closely linked to nitrate signaling, uptake and reduction.
Excessive ammonium assimilation by plastidic glutamine synthetase causes ammonium toxicity in Arabidopsis thaliana.

TL;DR: In this article, it was shown that ammonium assimilation by GLUTAMINE SYNTHETASE 2 (GLN2) localized in the plastid rather than ammonium accumulation is a primary cause for toxicity, which challenges the textbook knowledge.
Distinct responses of the mitochondrial respiratory chain to long- and short-term high-light environments in Arabidopsis thaliana.
Keisuke Yoshida,Keisuke Yoshida,Chihiro Watanabe,Takushi Hachiya,Danny Tholen,Masaru Shibata,Ichiro Terashima,Ko Noguchi +7 more
TL;DR: It is suggested that AOX plays an important role in rapid acclimation of the respiratory chain to sHL, which may support efficient photosynthetic performance and sustain the fast plant growth.

Effects of AOX1a Deficiency on Plant Growth, Gene Expression of Respiratory Components and Metabolic Profile Under Low-Nitrogen Stress in Arabidopsis thaliana
Chihiro Watanabe,Takushi Hachiya,Kentaro Takahara,Maki Kawai-Yamada,Hirofumi Uchimiya,Yukifumi Uesono,Ichiro Terashima,Ko Noguchi +7 more
TL;DR: The results indicated that the N-limited stress induced AOX expression in A. thaliana plants may not play essential roles under stress due to low-N alone, and the C/N balance under low- N stress may be tightly regulated by systems other than AOX.
