12 GABA in Plants Neurotransmitters and GHB Academic Article uri icon


  • Abstract γ-Aminobutyric acid (GABA) is a four-carbon non-protein amino acid conserved from bacteria to plants and vertebrates. In the latter it is mainly known as a neurotransmitter. The enzymes that synthesize and catabolize GABA constitute a metabolic pathway known as the GABA shunt which bypasses two steps of the tricarboxylic acid cycle. Functional genomics tools using Arabidopsis as a model system revealed that the GABA shunt is imperative for normal plant development and for response to stress, and suggest roles for …
