It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractThis invention involves a cloning or expression vector comprising a gene which encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) polypeptide which, when expressed in a plant cell contains a chloroplast transit peptide which allows the polypeptide, or an enzymatically active portion thereof, to be transported from the cytoplasm of the plant cell into a chloroplast in the plant cell, and confers a substantial degree of glyphosate resistance upon the plant cell and plants regenerated therefrom.The EPSPS coding sequence may be ligated to a strong promoter, such as the 35S promoter from cauliflower mosaic virus, to create a chimeric gene. Such genes can be inserted into plant transformation vectors, and subsequently introduced into plant cells. Plant cells transformed using such genes and plants regenerated therefrom have been shown to exhibit a substantial degree of glyphosate resistance. | InventorsApplicationNo. 478794 filed on 02/12/1990US Classes:47/58.1R, PROCESS435/69.1, Recombinant DNA technique included in method of making a protein or polypeptide435/69.7, Fusion proteins or polypeptides435/69.8, Signal sequence (e.g., beta-galactosidase, etc.)435/70.1, Using tissue cell culture to make a protein or polypeptide435/183, ENZYME (E.G., LIGASES (6. ), ETC.), PROENZYME; COMPOSITIONS THEREOF; PROCESS FOR PREPARING, ACTIVATING, INHIBITING, SEPARATING, OR PURIFYING ENZYMES504/117, Micro-organisms or from micro-organisms (e.g., fermentates, fungi, bacteria, viruses, etc.)504/195, Hetero ring containing504/197, Plural ring nitrogens in the hetero ring504/205, Additional -C(=X)-, or additional nitrogen attached indirectly to the phosphorus by acyclic nonionic bonding504/206, Containing -C(=X)X-, wherein the X`s are the same or diverse chalcogens (e.g., N-phosphonomethylglycines, etc.)800/300, Herbicide resistant plant which is transgenic or mutant800/300.1The plant is maizeField of Search435/69.1, Recombinant DNA technique included in method of making a protein or polypeptide435/183, ENZYME (E.G., LIGASES (6. ), ETC.), PROENZYME; COMPOSITIONS THEREOF; PROCESS FOR PREPARING, ACTIVATING, INHIBITING, SEPARATING, OR PURIFYING ENZYMES435/69.7, Fusion proteins or polypeptides435/69.8, Signal sequence (e.g., beta-galactosidase, etc.)435/70.1Using tissue cell culture to make a protein or polypeptideExaminersPrimary: Fox, David T.Attorney, Agent or FirmUS Patent References4940835Glyphosate-resistant plantsIssued on: 07/10/1990 Inventor: Shah, et al.
