摘要

Compositions and methods relating to the use of sulfonylurea-mediated control of gene expression are provided. Compositions include sulfonylurea responsive chemical switches wherein the gene expression is regulated by a sulfonylurea compound. Compositions also include polynucleotides encoding the polypeptides as well as constructs, vectors, prokaryotic and eukaryotic cells, and eukaryotic organisms including plants and seeds comprising the polynucleotide, and/or produced by the methods. Also provided are methods to regulate expression of a polynucleotide of interest in a cell or organism, and methods to modify a genome, including in a plant or plant cell.
