GABA signaling: a conserved and ubiquitous mechanism.
In plants, research on gamma-aminobutyric acid (GABA) has focused on its role as a metabolite, mainly in the context of responses to biotic and abiotic stresses. By contrast, studies of GABA in vertebrates have concentrated mainly on its role as a neurotransmitter and signaling molecule. Here, we discuss recent findings that point towards a possible role for GABA as a signaling molecule in plants.
