EXOGENOUS REGULATION OF GENE EXPRESSION IN PLANTS

摘要

Disclosed is a method for the exogenous regulation of gene expression in plants, which comprises obtaining a plant incapable of regulating at least one gene or gene family, or at least one heterologous gene, due to the deactivation of at least one endogenous signal transduction cascade which regulates the gene in the plant, and applying a chemical regulator to the plant at a time when expression of the gene is desired. Also disclosed is a method of assaying for chemicals capable of exogenously regulating gene expression, as well as modified plants, plant tissue and plant cells incapable of regulating at least one gene, gene family or heterologous gene due to at least one deactivated signal transduction cascade, per se.
