The present invention provides promoters from plants capable of driving gene expression in plant cells. The promoters vary in strength and in tissue specificity, and can be used to facilitate the development of transgenic plants in which tissue preferred expression, constitutive expression, and the strength of transgene expression is either more or less critical.

Rice promoters for regulation of plant expression

The invention relates to methods of producing plants with increased resistance to pathogen infection by expressing disease resistance genes in the plants and transgenic plants having enhanced pathogen resistance.

Plant disease resistance genes

The present invention relates to methods of replacing nucleotides in target nucleic acid sequences using DNA-LNA chimeras. The method of the present invention provides for replacing a first nucleotide in a target sequence by exposing the target sequence to a DNA-LNA heteropolymer and thereby replacing the first nucleotide with a second nucleotide. The invention also features the DNA-LNA chimeras themselves as well as methods of making them.

Locked nucleic acid containing heteropolymers and related methods

The invention provides novel stress tolerant transgenic plants which express trehalose 6-phosphate synthase and trehalose-6-phosphate phosphatase in their plastids.

Expression of trehalose 6-phosphate synthase and trehalose 6-phosphate phosphatase in plant plastids

The present invention is drawn to a method of controlling gene expression in plants. Specifically, the method comprises obtaining a transgenic plant comprising at least two receptor expression cassettes and at least one target expression cassette. The first receptor expression cassette comprises a nucleotide sequence for a 5' regulatory region operably linked to a nucleotide sequence which encodes a first receptor polypeptide, and a 3&#x2032; termination region. The second receptor expression cassette comprises a nucleotide sequence for a 5&#x2032; regulatory region operably linked to a nucleotide sequence which encodes a second receptor polypeptide, and a 3&#x2032; termination region. The target expression cassette comprises a nucleotide sequence for a 5&#x2032; regulatory region operably linked to a nucleotide sequence which encodes a target polypeptide, and a 3&#x2032; termination region, wherein the 5&#x2032; regulatory region of the target expression cassette is activated by the first and second receptor polypeptides in the presence of one or more chemical ligands which are complementary to the ligand binding domain of the receptor polypeptides, whereby expression of the target polypeptide is accomplished. The method is useful for controlling various traits of agronomic importance, such as plant fertility.

Control of gene expression in plants by receptor mediated transactivation in the presence of a chemical ligand

The invention provides novel transgenic plants which express trehalose biosynthetic genes, e.g., under control of an inducible promoter, which are developmentally normal, together with methods for improving stress tolerance in said plants, methods of improving food quality, and other methods of making and using the plants of the invention. The invention also provides nucleotide sequences encoded novel trehalose biosynthetic enzymes.

Expression of trehalose 6-phosphate synthase in plant plastids

The invention provides novel methods of processing grain, such as corn and soybeans, utilizing thioredoxin and/or thioredoxin reductase to enhance extractability and recovery of starch and protein. The invention further provides novel transgenic plants expressing thermostable thioredoxin and/or thioredoxin reductase.

Grain processing method and transgenic plants useful therein

The present invention is drawn to a method of controlling gene expression in plants. Specifically, the method comprises transforming a plant with a USP receptor expression cassette which encodes a USP receptor and at least one target expression cassette which encodes a target polypeptide. Contacting said transformed plant with juvenile hormone or one of its agonists activates expression of the target polypeptide in the presence of said USP receptor polypeptide. Optionally, additional &ldquo;secondary&rdquo; receptor expression cassettes may be used, wherein the secondary receptor expression cassette encodes a receptor polypeptide distinct from USP. The method is useful for controlling various traits of agronomic importance, such as plant fertility. Also disclosed is a method of identifying previously unknown ligands for USP. Substances to be tested are identified by placing them in contact with plant cells transformed with a USP receptor expression cassette and a target expression cassette. The target expression cassette encodes a reporter polypeptide whose expression can be determined quantitatively or qualitatively, whereby the test substance is identified as a ligand for USP.
