Emerging Roles of γ Aminobutyric Acid (GABA) Gated Channels in Plant Stress Tolerance

The signaling role for gamma-Aminobutyric acid (GABA) has been documented in animals for over seven decades. However, a signaling role for GABA in plants is just beginning to emerge with the discovery of putative GABA binding site/s and GABA regulation of anion channels. In this review, we explore the role of GABA in plant growth and development under abiotic stress, its interactions with other signaling molecules and the probability that there are other anion channels with important roles in stress tolerance that are gated by GABA.

Automated summary

The signaling role of gamma-aminobutyric acid (GABA) in plants is still emerging, with potential impacts on plant growth, development, and stress tolerance. Additionally, GABA may regulate stress tolerance in plants by modulating anion channels.
