This synopsis covers the compartmentation of γ-aminobutyrate (GABA) metabolism, highlighting recent progress with Arabidopsis (Arabidopsis thaliana) and raising questions about mitochondrial GABA and succinic semialdehyde (SSA) transport, the fate of succinic semialdehyde once it exits mitochondria, and biochemical interactions between GABA metabolism and related processes such as photorespiration.
