Anoxic stress induces a strong change in sugar, protein, and amino acid metabolism in higher plants. Sugars are rapidly consumed through the anaerobic glycolysis to sustain energy production. Protein degradation under anoxia is a mechanism to release free amino acids contributing in this way to maintaining the osmotic potential of the tissue under stress. Among free amino acids, a particular role is played by glutamic acid, being a precursor of some characteristic compounds of the anaerobic metabolism (alanine, γ-aminobutyric acid, and putrescine). The glutamine synthetase/glutamate synthase cycle contributes to ammonia reassimilation and primary assimilation of nitrate, and resynthesizes constantly glutamate for the synthesis of other compounds. Some polypeptides involved in these pathways are expressed under anoxia. The importance of amino acid metabolism for the response to anaerobic stress is discussed.
