Schematic representation of the central role of alanine during hypoxia and post-hypoxia recovery periods. HYPOXIA: Visualization of carbon flux from carbon storage compounds to alanine through AlaAT/NADH-GOGAT cycle. (POST-HYPOXIA) Visualization of alanine mobilization through AlaAT/GDH cycle and carbon flux towards TCA cycle. Scheme drawn by integrating data from transcriptomic and metabolomic studies and studies combining ¹⁵N and ¹³C labeling in various species such as Medicago truncatula, Lotus japonicus, Glycine max and Arabidopsis thaliana. AlaAT: Alanine aminotransferase; GDH: Glutamate Dehydrogenase GOGAT: Glutamne Oxoglutarate Aminotransferase.
