International audience. Summary statement Day respiration is a net flux resulting from several CO 2 ‐generating and CO 2 ‐fixing reactions, not only related to catabolism but also to anabolism. We review pieces of evidence that decarboxylating reactions are partly fed by carbon sources disconnected from current photosynthesis and how they reflect various metabolic pathways.

Leaf day respiration involves multiple carbon sources and depends on previous dark metabolism

Archive ouverte | Abadie, Cyril | CCSD

International audience. Abstract Day respiration ( R d ) is the metabolic, nonphotorespiratory process by which illuminated leaves liberate CO 2 during photosynthesis. R d is used routinely in photosynthetic models ...

Phloem Sap Composition: What Have We Learnt from Metabolomics?

Archive ouverte | Broussard, Louis | CCSD

International audience. Phloem sap transport is essential for plant nutrition and development since it mediates redistribution of nutrients, metabolites and signaling molecules. However, its biochemical composition ...

Non‐targeted 13 C metabolite analysis demonstrates broad re‐orchestration of leaf metabolism when gas exchange conditions vary

International audience. It is common practice to manipulate CO2 and O2 mole fraction during gas-exchange experiments to suppress or exacerbate photorespiration, or simply carry out CO2 response curves. In doing so, ...
