The heterotrimeric G protein complex, comprising G alpha, G gamma and G gamma subunits, is an evolutionarily conserved signaling molecular machine that transmits signals from transmembrane receptors to downstream target proteins. Plants conserved the core G protein elements, while developing their own regulatory systems differently from animals. Genetic evidence supports the conclusion that the heterotrimeric G proteins regulate shoot, root and epidermis development, as well as sugar sensing, hormone responsiveness and abiotic and biotic stress tolerance. This review is a compendium of the known morphological changes conferred by loss- and gain-of-function mutations of the G protein subunit genes across three higher land plant models, namely Arabidopsis, rice and maize.
