Abstract:
An isolated nucleic acid construct including a nucleic acid molecule encoding a light-labile, phytochrome A, a light-inducible promoter which is 5null to the nucleic acid molecule encoding a light-labile, phytochrome A, and a terminator region which is 3null to the nucleic acid molecule encoding a light-labile, phytochrome A is disclosed. Methods for regulating a plant's canopy architecture and regulating a plant's seed yield, which involve transgenic plants or transgenic plant seeds including an isolated nucleic acid construct according to the present invention, are also disclosed.
Abstract:
The present invention provides compositions with chitinase activity and methods for using such compositions to enhance resistance of plants to fungal infections.
Abstract:
The Arabidopsis NI16 gene was isolated in a yeast 2-hybrid screen via its interaction with the NIM1 protein and encodes a protein involved in the regulation of SAR gene expression in plants. NI16 is strongly induced in NIM1-overexpressing plants treated with benzo(1,2,3)thiadiazole-7-carbothioic acid S-methyl ester (BTH). The nucleic acid sequence of the Arabidopsis NI16 promoter is disclosed herein.
Abstract:
Methods of altering substrate specificity of beta-ketoacyl-ACP synthase, and engineered beta-ketoacyl-ACP synthases so produced are provided. DNA sequences and constructs for expression of engineered beta-ketoacyl-ACP synthases, as well as the novel beta-ketoacyl-ACP synthases produced therefrom are also provided. Such DNA sequences may be used for expression of the engineered beta-ketoacyl-ACP synthases in host cells, particularly seed cells of oilseed crop plants, for the modification of fatty acid composition.
Abstract:
The present invention provides a method for enhancing the production of RNAs or proteins in a plant host using either non-native 5null untranslated sequences or artificial leader sequences. Preferably, commercially useful proteins, polypeptides, or fusion products thereof are produced, such as, enzymes, antibodies, hormones, pharmaceuticals, vaccines, pigments, anti-microbial polypeptides, and the like. The non-native 5null untranslated enhancers may also be effective in many different types of transcription or translation systems, such as bacterial and animal systems.
Abstract:
Compositions and methods for enhancing or creating plant disease resistance to plant pests are provided. Transforming a plant with a novel rice Pi2-like disease resistance gene of the invention enhances disease resistance of the plant. Transformed plants, plant cells, tissues, and seed having enhanced disease resistance are also provided.
Abstract:
The present invention relates to the fields of molecular biology and plant biology. Specifically, the invention is directed to the methods for expressing spider silk proteins in plants and the synthesis and purification of spider silk proteins therefrom.
Abstract:
A method for selectively transducing retinal pigment epithelium (RPE) cells in an eye of a mammal, comprises administering to the mammal a vector particle exhibiting an AAV-4 capsid protein.
Abstract:
Pathogen-inducible plant promoters are identified. The promoters control expression of nullhypersensitive responsenull proteins, including a protease inhibitor, an isocitrate lyase, and a glycoprotein. Heterologous gene sequences are produced by operably linking a promoter according to the present invention with a gene to be expressed in a transformed plant. Transformed plants are made by transforming a vector with a heterologous gene according to the present invention and then transforming the plant with the transformed vector. The transformed plants are capable of expressing a pre-selected protein in response to challenge by a plant pathogen, for example tobacco blue moldnullP. tabacina.
Abstract:
Applicants have identified 5 mutants associated with hepatitis B virus resistance to adefovir, a nucleotide analogue antiviral drug widely employed in the therapy of hepatitis B. In accord with this invention, reverse transcriptase mutants rtN236T, rtA181V, rtA181T and their corresponding surface antigen mutants sL173F and sL172trunc are provided. The mutant proteins, antibodies thereto and nucleic acids encoding the mutants have diagnostic value in monitoring and adjusting patient therapy with adefovir and in the therapy of patients infected with the mutants.
