Abstract: The present invention relates to novel sulfonamide derivatives of formula (I), to processes and intermediates for preparing them, to plant growth regulator compositions comprising them and to methods of using them for controlling the growth of plants, improving plant tolerance to abiotic stress (including environmental and chemical stresses), inhibiting seed germination and/or safening a plant against phytotoxic effects of chemicals.

Abstract: The present invention sets forth small novel abscisic acid (ABA) receptor agonist scaffolds and compounds with potent in vivo activity. In some aspects, the present invention provides agricultural formulations and methods comprising the ABA receptor agonists described herein, such as methods of managing crop water use and improving stress tolerance (e.g., drought tolerance). In some preferred embodiments, the inventive compounds have improved properties relative to the current “best in-class” molecules quinabactin and its derivatives.

Abstract: Mutated PYR/PYL receptor polypeptides and mutated type 2C protein phosphatases (PP2Cs) are provided. In some embodiments, the mutated PYR/PYL receptor polypeptide is agonized by an orthogonal ligand that does not significantly agonize a wild-type PYR/PYL receptor polypeptide and comprises one or more mutations that disrupts binding to a wild-type PP2C, and the mutated PP2C comprises one or more mutations that disrupts binding to a wild-type PYR/PYL receptor polypeptide, wherein the mutated PYR/PYL receptor polypeptide and the mutated PP2C interact with each other.

Abstract: The present invention provides agonist compounds that activate ABA receptors, agricultural formulations comprising the agonist compounds, and methods of use for the compounds and formulations. The agricultural formulations are useful for inducing ABA responses in plant vegetative tissues, reducing abiotic stress in plants, and inhibiting germination of plant seeds. The compounds are also useful for inducing expression of ABA-responsive genes in cells that express endogenous or heterologous ABA receptors.
