摘要:
An expression cassette, operable in a recombinant host, comprising a heterologous DNA coding sequence encoding a protein, which is functional, alone or in cooperation with one or more additional proteins of catalyzing an oxidation step in the biological pathway, for conversion of cholesterol into hydrocortisone, which step is selected from the group consisting of: the conversion of cholesterol to pregnenolone; the conversion of pregnenolone to progesterone; the conversion of progesterone to 17&agr;-hydroxyprogesterone; the conversion of 17&agr;-hydroxyprogesterone to cortexolone; the conversion of cortexolone to hydrocortisone, and the corresponding control sequences effective in that host.
摘要:
The invention relates to the genetic manipulation of plants, particularly to the expression of nucleotide sequences from defense-related signaling genes. Isolated nucleotide sequences encoding a neoxanthin cleavage enzyme, an amino acid permease, and a novel protein are provided. Also provided are isolated nucleotide sequences comprising promoters that drive expression in a plant in an inducible or tissue-preferred manner. The nucleotide sequences find use in increasing the resistance of plants to pathogens and other stresses, modifying ABA metabolism in plants, modifying amino acid transport and content in plants, and regulating gene expression in plants. Additionally provided are isolated proteins, and transformed plants and seeds thereof.

The invention provides isolated Rar1 nucleic acids and their encoded proteins. The present invention provides methods and compositions relating to altering Rar1 concentration and/or composition of plants. The invention further provides recombinant expression cassettes, host cells, and transgenic plants.
摘要:
The invention relates to plants, especially transgenic plants, plant parts and plant cells overproducing an iron binding protein (e.g., ferritin) and having an enhanced resistance against a wide range of abiotic and biotic oxidative stress conditions (e.g., against treatment with paraquat or fusaric acid and against viral, bacterial or fungal infections). The invention also comprises nucleic acid sequences encoding an alfalfa ferritin or functional variants thereof and the use of such sequences for rendering plants resistant against oxidative stress conditions. The invention is useful for reducing environmental damages of crops caused by a wide variety of stress conditions.
摘要:
The present invention is directed to novel chimpanzee erythropoietin polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
摘要:
A method of dwarfing plants comprises controlling the expression of the genes involved in the dwarfism of the plants is provided. A molecule to be utilized for dwarfing plants is also provided. A single gene that causes the d1 mutation, which results in the dwarf abnormality of rice, was identified and isolated from a vast chromosomal region by the map-based cloning technique. This method enables, for example, creating ornamental plants and agricultural products with new commercial values, and therefore is useful especially in the areas of agriculture and horticulture.
摘要:
The invention is directed to LERK-6 as a purified and isolated protein, the DNA encoding the LERK-6, host cells transfected with cDNAs encoding LERK-6.
摘要:
DNA sequences coding for a TNF-binding protein and for the TNF receptor of which this protein constitutes the soluble domain. The DNA sequences can be used for preparing recombinant DNA molecules in order to produce TNF-binding protein and TNF receptor. Recombinant TNF-binding protein is used in pharmaceutical preparations for treating indications in which TNF has a harmful effect. With the aid of the TNF receptor or fragments thereof or with the aid of suitable host organisms transformed with recombinant DNA molecules containing the DNA which codes for the TNF receptor or fragments or modifications thereof, it is possible to investigate substances for their interaction with the TNF receptor and/or for their effect on the biological activity of TNF.
摘要:
Methods for obtaining a protein by culture of hybridoma cells, wherein said protein is an immunoglobulin, are disclosed. The methods involve culturing animal hybridoma cells in continuous presence of an alkanoic acid or salt thereof, which enhances protein production, wherein said alkanoic acid or salt thereof is present at 2 concentration range of 0.1 mM to 200 mM.
摘要:
The present invention relates to genetically attenuated superantigen toxin vaccines altered such that superantigen attributes are absent, however the superantigen is effectively recognized and an appropriate immune response is produced. The attenuated superantigen toxins are shown to protect animals against challenge with wild type toxin. Methods of producing and using the altered superantigen toxins are described.
