Patent number: 6350935Abstract: Expansins are proteins that induce extension in isolated plant cell walls in vitro and have been proposed to disrupt non-covalent interactions between hemicellulose and cellulose microfibrils. Because the plant primary cell wall acts as a constraint to cell enlargement, this process may be integral to plant cell expansion and studies of expansins have focused on their role in growth. We have discovered an expansin (Ex1) from tomato, melon and strawberry that is highly abundant and specifically expressed in ripening fruit, a developmental period when growth has ceased but when selective disassembly of cell wall components is pronounced. Also disclosed are expression vectors containing the Ex1 coding sequence, expression vectors containing an Ex1 sequence in the antisense orientation, Ex1 proteins, and transgenic plants which express both sense and antisense exogenous Ex1.Type: GrantFiled: July 27, 1999Date of Patent: February 26, 2002Assignee: The Regents of the University of CaliforniaInventors: Alan B. Bennett, Jocelyn K. C. Rose

Patent number: 6235974Abstract: The present invention relates to a method of imparting pathogen resistance to plants. This involves applying a hypersensitive response elicitor polypeptide or protein in a non-infectious form to a plant seed under conditions where the polypeptide or protein contacts cells of the plant seed. The present invention is also directed to a pathogen resistance imparting plant seed. Alternatively, transgenic plant seeds containing a DNA molecule encoding a hypersensitive response elicitor polypeptide or protein can be planted in soil and a plant can be propagated from the planted seed under conditions effective to impart pathogen resistance to the plant.Type: GrantFiled: December 3, 1997Date of Patent: May 22, 2001Assignee: Cornell Research Foundation, Inc.Inventors: Dewen Qiu, Zhong-Min Wei, Steven V.

Patent number: 6084152Abstract: The invention relates to a transgenic plant that produces high levels of superoxide dismutase (SOD) and to a method for producing the transgenic plant. The hypocotyl section of seedlings is co-cultured with Agrobacterium transformant and regenerated by adventitious shoot induction and by root induction, where the Agrobacterium transformant contains an expression vector that comprises the promoter of a fruit-dominant ascorbate oxidase gene, an SOD gene isolated from cassava, and an herbicide-resistant bar gene. The present invention also relates to a method for inducing adventitious shoot from hypocotyl sections in plant tissue culture, thus providing a method for the efficient production of transgenic plants maintaining higher SOD activity in fruits. Therefore, the SOD transgenic cucumber of the present invention can be used for cosmetics, additives in functional foods, and medicines as well as having tolerance to herbicides and environmental stresses.Type: GrantFiled: April 14, 1999Date of Patent: July 4, 2000Assignee: Korea Institute of Science and TechnologyInventors: Sang Soo Kwak, Jae-Whune Kim, Haeng-Soon Lee, Suk Yoon Kwon
