The use of preselected combination of N. tabacum varieties and Agrobacterium strains, optionally including one or more improvements to the transient expression-based methods of the invention, enables the production of large quantities of a heterologous polypeptides economically and in a short period of time.Type: ApplicationFiled: January 17, 2012Publication date: October 2, 2014Applicant: PHILIP MORRIS PRODUCTS S.A.Inventors: Julien Beuchat, Prisca Campanoni, Shunhong Dai, Claudio Facchinetti, Nicolas Lugon-Moulin, Karen Oishi, Gustavo Ramirez, Sandrine Roesti, Helene Laparra, Rosa Cabrera

Patent number: 8847009Abstract: The invention provides methods for identifying regenerated transformed plants and differentiated transformed plant parts, obtained without subjecting plant cells to selective conditions prior to regenerating the cells to obtain differentiated tissues. In particular embodiments, the plant cells are corn plant cells. Methods for growing and handling plants, including identifying plants that demonstrate specific traits of interest are also provided.Type: GrantFiled: August 22, 2013Date of Patent: September 30, 2014Assignee: Monsanto Technology LLCInventor: Jyoti R. Rout

Patent number: 8829275Abstract: The invention provides methods and compositions for identifying transgenic seed that contain a transgene of interest, but lack a marker gene. Use of an identification sequence that results in a detectable phenotype increases the efficiency of screening for seed and plants in which transgene sequences not linked to a gene of interest have segregated from the sequence encoding a gene of interest.Type: GrantFiled: July 25, 2012Date of Patent: September 9, 2014Assignee: Monsanto Technology LLCInventors: Xudong Ye, Michael W. Petersen, Larry Gilbertson, David Walters, Susan Johnson, Shihshieh Huang, Paul S. Chomet
