Patent number: 7994394Abstract: Disease-inducible promoter sequences have been identified that may be used to produce transgenic plants that are both more resistant to disease than control plants, and are wild-type or nearly wild type in appearance. Any of these disease-inducible promoters may be incorporated into expression vectors that each comprise a defense response protein operably linked to the promoter. The expression vectors can be introduced into plants and the defense response protein then ectopically expressed. Transgenic plants transformed with many of these expression vectors have been shown to be more resistant to disease, in some cases, to more than one type of pathogen, and yet are similar to wild type plants in their morphology and development.Type: GrantFiled: April 23, 2007Date of Patent: August 9, 2011Assignee: Mendel Biotechnology, Inc.Inventors: Luc Adam, T. Lynne Reuber, Karen S. Century

Publication number: 20110126326Abstract: A new and strong transcriptional activation domain was identified from the Arabidopsis protein Ethylene Response Factor 98 (AtERF98). This domain has been designated as the “EDLL domain” and has a number of highly conserved amino acid residues that are found throughout the members of the AtERF98 family from plants, including in monocot and eudicot orthologs. The EDLL domain was shown to be highly active when it was fused to transcription factors from plant and yeast, and was also shown to have activation potential comparable to the widely-used VP16 activation domain derived from Herpes simplex. The EDLL domain was also active when it was targeted to a gene promoter by a sequence-specific DNA binding protein or by protein-protein interactions. Unlike other known activation domains such as VP16 and GAL4, the EDLL domain is relatively small in size, and being of plant origin, it is favored as a strong transcriptional activation tool for application in transgenic food crops.Type: ApplicationFiled: June 26, 2009Publication date: May 26, 2011Applicant: MENDEL BIOTECHNOLOGY, INC.Inventors: Shiv Tiwari, Roger Canales, T.

Publication number: 20090265813Abstract: Transcription factor polynucleotides and polypeptides incorporated into expression vectors have been introduced into plants and were ectopically expressed. Transgenic plants transformed with many of these expression vectors have been shown to be more resistant to disease (in some cases, to more than one pathogen), or more tolerant to an abiotic stress (in some cases, to more than one abiotic stress). The abiotic stress may include salt, hyperosmotic stress, heat, cold, drought, or low nitrogen conditions.Type: ApplicationFiled: August 31, 2006Publication date: October 22, 2009Applicant: Mendel Biotechnology , Inc.Inventors: Neal I.

Publication number: 20090138981Abstract: Transcription factor polynucleotides and polypeptides incorporated into nucleic acid constructs, including expression vectors, have been introduced into plants and were ectopically expressed. Transgenic plants transformed with many of these constructs have been shown to be more resistant to disease (in some cases, to more than one pathogen), or more tolerant to an abiotic stress (in some cases, to more than one abiotic stress). The abiotic stress may include, for example, salt, hyperosmotic stress, water deficit, heat, cold, drought, or low nutrient conditions.Type: ApplicationFiled: March 17, 2008Publication date: May 28, 2009Applicant: Mendel Biotechnology, Inc.Inventors: Peter P.

Publication number: 20080301836Abstract: The invention relates to a method for selection of modified plant transcription factor polypeptides, polynucleotides that encode them, and methods of producing transgenic plants having advantageous properties, including increased biotic resistance and abiotic stress tolerance, as compared to wild-type or control plants. Without modifications, the transcription factor sequences, when overexpressed in plants, often produce adverse morphological and developmental effects. The disclosed method allows selection of modifications that mitigate these adverse morphological and developmental effects.Type: ApplicationFiled: May 19, 2008Publication date: December 4, 2008Applicant: Mendel Biotechnology, Inc.Inventors: Karen S.
