Heterotrimeric G-proteins are complexes that regulate important signalling pathways essential for growth and development in both plants and animals. Although plant cells are composed of the core components (Gα, Gβ and Gγ subunits) found in animal G-proteins, the complexities of the architecture, function and signalling mechanisms of that in animals are dissimilar to what has been identified in some plants. Current studies on plants G-proteins have improved the knowledge of essential physiological and agronomic properties which when harness could potentially impact global food security. Extensive studies on the molecular mechanisms underlying these properties in diverse plant species will be imperative in improving our current understanding of G-protein signalling pathways involved in plant growth and development. The advancement of G-protein signalling network in distinct plant species could significantly aid in better crop improvement. This review summarizes current progress, novel discoveries and future prospects of this area in crop improvement.
