Polynucleotides incorporated into nucleic acid constructs have been introduced into plants and were ectopically expressed. The encoded polypeptides of the invention have been shown to confer at least one regulatory activity and confer earlier flowering, longer floral organ retention, increased cold tolerance, greater tolerance to water deprivation, altered carbon-nitrogen balance sensing, increased low nitrogen tolerance, and/or increased tolerance to hyperosmotic stress as compared to a control plant.

Plant tolerance to low water, low nitrogen and cold II

Transcription factor polynucleotides and polypeptides incorporated into nucleic acid constructs, including expression vectors, have been introduced into plants and were ectopically expressed. Transgenic plants transformed with many of these constructs have been shown to be more resistant to disease (in some cases, to more than one pathogen), or more tolerant to an abiotic stress (in some cases, to more than one abiotic stress). The abiotic stress may include, for example, salt, hyperosmotic stress, water deficit, heat, cold, drought, or low nutrient conditions.

Stress tolerance in plants

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 improved tolerance to drought, shade, and low nitrogen conditions, as compared to wild-type or reference plants.

Plant transcriptional regulators

Water deficit-inducible promoter sequences were identified that may be used to produce transgenic plants that are more tolerant to water deficit and related hyperosmotic stresses than control plants, and yet are wild-type or nearly wild type in appearance. Any of these water deficit-inducible promoters may be incorporated into an expression vector that comprises a polynucleotide regulated by one such promoter and which encodes a polypeptide that, when ectopically expressed, improves water deficit tolerance in plants that are similar to control plants in their morphology and development.

Water deficit-inducible promoters

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 compared to a reference plant. Sequence information related to these polynucleotides and polypeptides can also be used in bioinformatic search methods and is also disclosed.

Polynucleotides and polypeptides in plants

MYB-related transcriptional regulators that confer altered root hare, trichome morphology, and increased tolerance to abiotic stress in plants

The present invention provides nucleic acid constructs, including plasmids, expression vectors or expression cassettes comprising polynucleotides encoding CCAAT-binding transcription factor polypeptides that have the ability to increase a plant's tolerance to abiotic stress. Polynucleotides encoding functional CCAAT-binding transcription factors were incorporated into expression vectors, introduced into plants, and ectopically expressed. The encoded polypeptides of the invention significantly increased the cold and water deficit tolerance of the transgenic plants, as compared to tolerance to these stresses of control plants.

Plants with improved water deficit and cold tolerance

The invention relates to plant transcription factor polypeptides, polynucleotides that encode them, homologs from a variety of plant species, variants of naturally-occurring sequences, and methods of using the polynucleotides and polypeptides to produce transgenic plants having advantageous properties, including improved cold and 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.

Plant transcriptional regulators of abiotic stress

Plant tolerance to low water, low nitrogen and cold

Polynucleotides incorporated into expression vectors have been introduced into plants and were ectopically expressed. The encoded polypeptides of the invention have been shown to confer at least one regulatory activity and confer greater size, greater organ size, greater biomass, greater yield, curlier leaves, darker coloration, greater tolerance to water deprivation, delayed flowering, delayed development, delayed senescence, greater tolerance to cold, and/or greater tolerance to hyperosmotic stress as compared to a control plant.
