    摘要: The invention relates to the regulation of gene expression, particularly to methods and compositions for regulating gene expression in plants. Expression cassettes comprising a polynucleotide molecule of interest operably linked to the Brachytic2 (Br2) promoter, or a functional fragment or variant thereof, are provided. Methods of using such expression cassettes, as well as plant cells, plant tissues, plants, and seeds transformed with these expression cassettes, are additionally provided. The methods and compositions find use in regulating the expression of a polynucleotide molecule of interest in a plant.

    摘要: The present invention provides a composition and method for regulating expression of heterologous nucleotide sequences in a plant. The composition is a novel nucleic acid sequence for a promoter. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequence is also provided. The method comprises transforming a plant cell to contain a heterologous nucleotide sequence operably linked to the promoter of the present invention and regenerating a stably transformed plant from the transformed plant cell.

    摘要: The present invention provides for rapid and large scale evaluation of expression of, or function of, nucleotide sequences in plants. The invention comprises three specific components which provide for fast and large scale evaluation of nucleotide sequences. The first component includes delivery in either a single event a library of different engineered vectors or a single engineered vector for a single target nucleotide sequence comprising sequences the function of which is desired to be known in plant cells. Surprisingly, applicants have discovered that, the introduction of multiple vectors to plant cells predominantly results in individual transgenic plants which contain only a single transformation event. The second feature of the invention involves a highly transformable, fast cycling and/or miniature size plant and the final step involves mass scale analysis of T0 plants for various phenotypes and plasmid rescue to identify the nucleotide sequence present in a particular phenotype.
