The heterotrimeric G protein complex, comprising Galpha, Gbeta and Ggamma 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; Arabidopsis, rice and maize.
