In animals, a number of extracellular signals to modify specific cellular processes via specific receptors that activate a variety of G protein heterotrimers Activated G proteins are able to induce intracellular signaling pathways through activation of effectors mainly catalyze formation of second messenger . In plants identified a single or more than two proteins ( and their encoding genes ) subunits properties (Ga, Gb and Gg ) heterotrimerowych G proteins , and although the association was not detected in the heterotrimer , it can be foreseen that in the signal transduction may be involved few types of heterotrimers G proteins also identified a few proteins that receptor and effector function , and G regulatory protein pathway requires confirmation . Understanding the process and the role of G protein signaling pathway in plants can still be described as fragmented. Description of this pathway therefore requires further intensive research, in which a favorable circumstance is to demonstrate that pharmacological modification of the activity of G proteins affects both the effects caused by plant hormones ( and other signaling molecules ) , as well as on a number of physiological processes. The scope of research approaches also extend subunit mutants lacking Ga and Gb , and transformants overexpressing these proteins .
