Abstract:
The invention relates to transmembrane receptors for which the endogenous ligand has not been identified, and specifically to a plant GPCR (“GCR1”) that has been altered to establish constitutive activity of the receptor. In some embodiments, the altered versions of GCR1 are used for the direct identification of candidate compounds as receptor agonists, inverse agonists or partial agonists for use in, for example and not limitation, herbicidal relevance; germination; growth elongation; seed dormancy; and fruit and vegetable ripening and development. In some embodiments, altered versions of GCR1 are used to modulate physiological processes in a plant. The invention further relates to plants comprising constitutively activated non-endogenous GPCRs.
