processes for suppressing, retarding or otherwise reducing expression of a target gene in a plant cell

摘要

"processes for suppressing, retarding or otherwise reducing expression of a target gene in a cell, tissue or organ and for conferring resistance or immunity to a viral pathogen on an entire cell, tissue, organ or organism, a synthetic gene capable of suppressing , retard or otherwise reduce expression of a target gene of an entire cell, tissue, organ or organism, gene construction, use thereof, and whole cell, tissue, organ or organism "The present invention relates generally a process of modifying gene expression and synthetic genes for modifying endogenous gene expression of a cell, tissue or organ of a transgenic organism, in particular a transgenic animal or plant. more particularly, the present invention utilizes recombinant DNA technology to post-transcriptionally modify or modulate expression of a target gene from an internal cell, tissue, organ or organism, thereby producing new phenotypes. Also provided are novel synthetic genes and gene constructs that are capable of repressing the delay in or otherwise reducing the expression of an endogenous gene or target gene of an organism when introduced into it.
