Abstract

Floral nectar, a vital nutrition source for pollinators, contains diverse chemical compounds, including γ-aminobutyric acid (GABA), a prevalent nonproteinogenic amino acid. While GABA's physiological role is known and well-studied, its ecological significance in plant–pollinator interactions remains unclear. Recent studies on GABA's effects on pollinators’ preference, consumption, survival, physiology, and behavior show varying outcomes according to the species, indicating a complex relationship. GABA consumption impacts motor function and cognitive abilities, potentially influencing pollination efficiency. Future research addressing diverse concentrations, species, and behavioral aspects is crucial for comprehensively understanding GABA's ecological role in plant–pollinator interactions.
