Patent number: 6603065Abstract: A novel process for the direct transfer of foreign genes to plant genomes is described. The novel process comprises placing a gene under the control of plant expression signals and transferring it, by contact with protoplasts without the aid of natural systems for infecting plants, direct to plant cells from which genetically transformed plants can subsequently be derived.Type: GrantFiled: November 29, 2000Date of Patent: August 5, 2003Assignee: Syngenta Investment CorporationInventors: Jerzy Paszkowski, Ingo Potrykus, Barbara Hohn, Raymond Douglas Shillito, Thomas Hohn, Michael William Saul, Vaclav Mandak

Patent number: 6376234Abstract: The present invention relates to a novel method of inserting viral DNA, which optionally may contain cargo-DNA, into plants or viable parts thereof, but preferably into plants of the monocotyledon class, and most preferably into plants of the family Gramineae, using suitable transfer microorganisms. Further comprised by the invention are recombinant DNA, plasmid and vector molecules suitably adapted to the specific conditions of the process according to the invention and the transgenic plant products obtainable in accordance with the said process.Type: GrantFiled: October 28, 1996Date of Patent: April 23, 2002Assignees: Ciba-Geigy, Mycogen Plant Science, Inc.Inventors: Nigel Harry Grimsley, Barbara Hohn, Thomas Hohn, Jeffrey William Davies, Margaret Irene Boulton

Patent number: 4304863Abstract: The present invention is directed to a process for the production of hybrid bacteria, characterized in that(a) a hybrid plasmid having only one cos site of a lambda or a lambdoid phage is produced from (1) a bacterial plasmid of not more than 21 Megadaltons and having only one cos site of a lambda or a lambdoid phage and (2) a foreign DNA fragment,(b) the resulting hybrid plasmid is packaged with the lysate of a lambda or lambdoid phage and(c) the packaging product is transduced into Escherichia coli whereby hybrid bacteria are formed.Type: GrantFiled: March 30, 1979Date of Patent: December 8, 1981Assignee: Gesellschaft fur Biotechnologische Forschung mbHInventors: John Collins, Barbara Hohn
