It has been 75 yr since leaf respiratory metabolism in the light (day respiration) was
identified as a low‐flux metabolic pathway that accompanies photosynthesis. In principle, it …

The saccharopine pathway (SACPATH) involves the conversion of lysine into α-
aminoadipate by three enzymatic reactions catalyzed by the bifunctional enzyme lysine …

Plant respiration is a foundational biological process with the potential to be optimized to
improve crop yield. To understand and manipulate the outputs of respiration, the inputs of …

Abstract Glycolate, malate, lactate, and 2-hydroxyglutarate are important 2-hydroxy acids
(2HA) in plant metabolism. Most of them can be found as D-and L-stereoisomers. These …

The tricarboxylic acid (TCA) cycle, a crucial component of respiratory metabolism, is
composed of a set of eight enzymes present in the mitochondrial matrix. However, most of …

Highlights•Methods for stable isotope labeling of plants for metabolomics are
reviewed.•Stable isotope labeling can improve metabolomics annotation and …

Ammonium nutrition often represents an important growth-limiting stress in plants. Some of
the symptoms that plants present under ammonium nutrition have been associated with pH …

Cytochrome c oxidase is the last respiratory complex of the electron transfer chain in
mitochondria and is responsible for transferring electrons to oxygen, the final acceptor, in the …

Leaf senescence is a long developmental process important for nutrient management and
for source to sink remobilization. Constituents of the mesophyll cells are progressively …

Glutamate (Glu) is the cornerstone of nitrogen assimilation and photorespiration in
illuminated leaves. Despite this crucial role, our knowledge of the flux to Glu de novo …
