Abstract: The invention relates to plant transcription factor polypeptides, polynucleotides that encode them, homologs from a variety of plant species, and methods of using the polynucleotides and polypeptides to produce transgenic plants having advantageous properties, including disease stress and abiotic stress tolerance, as compared to wild-type or control plants. The invention also pertains to expression systems that may be used to regulate these transcription factor polynucleotides, providing constitutive, transient, inducible and tissue-specific regulation.

Abstract: The invention relates to plant transcription factor polypeptides, polynucleotides that encode them, homologs from a variety of plant species, and methods of using the polynucleotides and polypeptides to produce transgenic plants having advantageous properties, including increased biomass or improved cold or other osmotic stress tolerance, as compared to wild-type or reference plants. The invention also pertains to expression systems that may be used to regulate these transcription factor polynucleotides, providing constitutive, transient, inducible and tissue-specific regulation.

Abstract: The present invention provides a high-throughput method for identifying a polynucleotide which encodes a transcription factor for controlling the expression of one or more genes in a pathway. In particular, the method is useful for identifying a transcription factor for controlling a gene in a biosynthetic pathway. The invention further provides polynucleotides encoding such transcription factors for controlling the expression of a gene in a biosynthetic pathway, transgenic cells expressing at least one such polynucleotide, and methods for isolating metabolites from such cells or plants.
Abstract: Recombinant polynucleotides and methods for modifying the phenotype of a plant are provided. In particular, the phenotype that is being modified is a plant's biomass. The method comprises altering the levels of a transcription factor that is introduced into the plant or that is endogenous to the plant to obtain a plant with a larger biomass.
Abstract: Plants transformed with a plant APZ transcription factor encoding polynucleotide, isolated from Arabidopsis, that enhances tolerance to fungal diseases, especially fungal diseases caused by Fusarium, Erysiphe, Sclerotinia and Botrytis.

Abstract: Recombinant proteins comprising on or more mitochondrial leader peptide sequences and a domain having herbicidal sulfonamide-insensitive dihydropteroate synthase activity are disclosed. Transformation of plants with nucleic acids that encode this mitochondrially-targeted recombinant protein is also provided. Such transformed plants exhibit resistance to herbicidal sulfonamides, such as asulam, and therefore may be cultivated where such herbicides are being used to control weed growth.
