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 those in animals are dissimilar to those identified in some plants. Current studies on plant G‐proteins have improved knowledge of the essential physiological and agronomic properties, which when harnessed, 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 networks in distinct plant species could significantly aid in better crop development. This review summarizes current progress, novel discoveries and future prospects for this area in potential crop improvement.

植物异源三聚体G蛋白的信号转导。

异三聚体G蛋白是调节重要信号通路的复合物，这些信号通路对于植物和动物的生长发育至关重要。尽管植物细胞由动物G蛋白中的核心成分（Gα，Gβ和Gγ亚基）组成，但动物体内的结构，功能和信号传导机制的复杂性与某些植物所鉴定的不同。目前对植物G蛋白的研究提高了人们对基本生理和农学特性的认识，如果加以利用，可能会影响全球粮食安全。在不同的植物物种中对这些特性潜在的分子机制进行广泛的研究对于增进我们对植物生长和发育所涉及的G蛋白信号通路的当前理解至关重要。G蛋白信号网络在不同植物物种中的发展可以显着促进作物的更好生长。这篇综述总结了该领域在潜在作物改良方面的最新进展，新颖发现和未来前景。
