Patent number: 8624081Abstract: The relationship between F-box proteins and proteins involved in the ethylene response in plants is described. In particular, F-box proteins may bind to proteins involved in the ethylene response and target them for degradation by the ubiquitin/proteasome pathway. The transcription factor EIN3 is a key transcription factor mediating ethylene-regulated gene expression and morphological responses. EIN3 is degraded through a ubiquitin/proteasome pathway mediated by F-box proteins EBF1 and EBF2. The link between F-box proteins and the ethylene response is a key step in modulating or regulating the response of a plant to ethylene. Described herein are transgenic plants having an altered sensitivity to ethylene, and methods for making transgenic plant having an altered sensitivity to ethylene by modulating the level of activity of F-box proteins. Methods of altering the ethylene response in a plant by modulating the activity or expression of an F-box protein are described.Type: GrantFiled: January 27, 2011Date of Patent: January 7, 2014Assignee: Salk Institute for Biological StudiesInventors: Hongwei Guo, Joseph R.

Patent number: 8168860Abstract: A gene expression system for controllable expression of ethylene response in a plant cell includes an activation cassette comprising a DNA-binding domain that recognizes a response element; an ecdysone receptor ligand binding domain; and an activation domain; and a target cassette comprising an inducible promoter, which comprises, in operative association, the response element and a minimal promoter responsive to the activation domain. The inducible promoter controls the expression of a nucleic acid sequence that encodes a selected protein that modifies sensitivity to ethylene in the plant. Interaction among the components of the activation cassette and target cassette, when in a plant cell, in the presence of an inducing composition, modulates expression of the selected protein and selectively modulates ethylene sensitivity in the plant cell. This modulation in the expression of the protein is controlled by the timing, the concentration and the duration of the application of the inducing composition.Type: GrantFiled: September 12, 2008Date of Patent: May 1, 2012Assignee: Rohm and Haas CompanyInventors: Jeffrey L.

The genes involved in producing this phenotype include 1-Aminocyclopropane-1-Carboxylate (“ACC”) synthase, ACC oxidase, ACC deaminase, ethylene response sensor (“ERS”), ethylene resistant (“ETR”), and ethylene insensitive (“EIN”).Type: ApplicationFiled: March 19, 2007Publication date: August 28, 2008Applicant: The Regents of the University of CaliforniaInventors: Daniel R. Gallie, Todd E. Young

Patent number: 7238857Abstract: An ethylene-responsive transcription co-activator (MBF) acts on ethylene-responsive transcription factors (ERFs), which positively controls the expression of ethylene-responsive plant genes. A plant is transformed by the gene of the co-activator, and a promoter that may increase or decrease responsiveness to ethylene depending on its alignment. A method for controlling the responsiveness of plants to ethylene transforms a plant comprising an ERF-dependent gene, which positively control the expression of ethylene responsive genes of plants. This transcription co-activator gene is applied to control ethylene response of plants.Type: GrantFiled: February 6, 2003Date of Patent: July 3, 2007Assignee: Japan and Science and Technology AgencyInventors: Ken-ichi Yamazaki, Susumu Hirose

Engineering single-gene-controlled staygreen potential into plants utilizing ACC synthase from maize
Patent number: 7230161Abstract: The enzymes of the ACC synthase family are used in producing ethylene. Nucleotide and polypeptide sequences of ACC synthases are provided along with knockout plant cells having inhibition in expression and/or activity in an ACC synthase and knockout plants displaying a staygreen phenotype, a male sterility phenotype, or an inhibition in ethylene production. Methods for modulating staygreen potential in plants, methods for modulating sterility in plants, and methods for inhibiting ethylene production in plants are also provided.Type: GrantFiled: June 22, 2004Date of Patent: June 12, 2007Assignees: Pioneer Hi-Bred International, Inc., The Regents of the University of CaliforniaInventors: Daniel R. Gallie, Robert Meeley, Todd Young -
Patent number: 7220587Abstract: Nucleic acid and polypeptide sequences are described which relate to an EIN6 gene, a gene involved in the plant ethylene response. Plant transformation vectors and transgenic plants are described which display an altered ethylene-dependent phenotype due to altered expression of EIN6 in transformed plants.Type: GrantFiled: June 13, 2005Date of Patent: May 22, 2007Assignees: The Salk Institute for Biological Studies, The Trustees of the University of PennsylvaniaInventors: Joseph R. Ecker, Ramlah Nehring, Robert B. McGrath

Patent number: 7119262Abstract: Since its introduction into North America over 170 years ago, the poinsettia has become a major ornamental potted plant, and is an important component of the U.S. floral industry. Susceptibility to insect pests and diseases caused by pathogens remains a problem for poinsettia production, even under greenhouse conditions. While chemical treatment can control certain insect pests and disease pathogens, such treatment can also have an adverse effect upon poinsettias. The methods described herein provide a means to genetically engineer transgenic poinsettia that express macromolecules capable of protecting the plant against the insects and pathogens. The production of transgenic plants can also be used to enhance the commercial value of poinsettia by controlling characteristics such as flower color.Type: GrantFiled: July 31, 1997Date of Patent: October 10, 2006Assignee: Sanford Scientific, Inc.Inventors: Franzine Smith, Tau-San Chou, Robert Eisenreich, John Sanford, Alan Blowers, Joyce Van Eck
