247 results about "Response element" patented technology

Response elements are short sequences of DNA within a gene promoter region that are able to bind specific transcription factors and regulate transcription of genes. Under conditions of stress, a transcription activator protein binds to the response element and stimulates transcription. If the same response element sequence is located in the control regions of different genes, then these genes will be activated by the same stimuli, thus producing a coordinated response.

Method for enriching and separating endogenous transcription factors and compounds thereof and concatenated transcription factor response elements special for method

The invention discloses a method for enriching and separating endogenous transcription factors and compounds thereof and concatenated transcription factor response elements special for the method. The method includes of designing multi-copy double-stranded DNA (deoxyribonucleic acid) binding elements according to the characteristic that transcription factors are bound with sequence-specific DNA elements, adding double-stranded DNA arms labeled with biotin to two ends of each DNA binding element by the aid of molecular cloning technology to form 'DNA baits', coupling the biotinylated DNA baits which are purified onto magnetic beads enveloped by streptavidin when in separation and purification of the endogenous transcription factors and compounds thereof, incubating the magnetic beads together with the prepared nucleoprotein, and finally separating and purifying the endogenous transcription factors and the compounds thereof from the nucleoprotein. Further, after the endogenous transcription factors and the compounds thereof are separated and purified, protein identification and function analysis of the transcription factors can be performed subsequently.

Marker-free gene deletion attenuated mutant strain of Edwardsiella tarda wild strain as well as relevant preparations and application thereof

The invention relates to a marker-free gene deletion attenuated mutant strain of an Edwardsiella tarda wild strain. The marker-free gene deletion attenuated mutant strain is an attenuated live vaccine of an Edwardsiella tarda virulent strain, which deletes the chorismic acid synthase gene aroC of the Edwardsiella tarda virulent strain, three types of secretion system response element genes of eseB, escA, eseC and eseD and an endogenous plasmid, preferably, the Edwardsiella tarda virulent strain is an Edwardsiella tarda virulent strain EIB202 with the preservation number of CCTCC No:M208068; the endogenous plasmid is a plasmid of pEIB202; and the marker-free gene deletion attenuated mutant strain of the Edwardsiella tarda virulent strain is an attenuated strain WED with the preservation number of CCTCC No:M2010278. The invention also provides relevant preparations and application of the marker-free gene deletion attenuated mutant strain. The attenuated mutant strain or relevant preparations eliminate the potential environment and safety risk of products existing in the traditional attenuated live vaccines generally and is a safe, effective and economic vaccine aiming at Edwardsiella tarda diseases of cultured fishes.

Compositions and methods for the modification of physiological responses in plants

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. Transgenic plant cells, tissues, organs and entire plants are provided, which in the presence of the inducing composition control ethylene sensitivity. Ethylene sensitivity and / or ethylene production in such transgenic plants and tissues may be controlled for purposes of manipulating ripening, flower senescence and other ethylene sensitive functions of the plant.
