Abstract: A new and strong transcriptional activation domain was identified from the Arabidopsis protein Ethylene Response Factor 98 (AtERF98). This domain has been designated as the “EDLL domain” and has a number of highly conserved amino acid residues that are found throughout the members of the AtERF98 family from plants, including in monocot and eudicot orthologs. The EDLL domain was shown to be highly active when it was fused to transcription factors from plant and yeast, and was also shown to have activation potential comparable to the widely-used VP16 activation domain derived from Herpes simplex. The EDLL domain was also active when it was targeted to a gene promoter by a sequence-specific DNA binding protein or by protein-protein interactions. Unlike other known activation domains such as VP16 and GAL4, the EDLL domain is relatively small in size, and being of plant origin, it is favored as a strong transcriptional activation tool for application in transgenic food crops.

Abstract: 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.

Abstract: Polynucleotides and polypeptides incorporated into expression vectors have been introduced into plants and were ectopically expressed. The polypeptides of the invention have been shown to confer at least one regulatory activity and confer increased yield, greater height, greater early season growth, greater canopy coverage, greater stem diameter, greater late season vigor, increased secondary rooting, more rapid germination, greater cold tolerance, greater tolerance to water deprivation, reduced stomatal conductance, altered C/N sensing, increased low nitrogen tolerance, increased low phosphorus tolerance, or increased tolerance to hyperosmotic stress as compared to the control plant as compared to a control plant.

Abstract: 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.

Abstract: The application describes producing polynucleotide variants of the AtHB 17 clade members and introducing the mutant variants into plants to improve plant traits. The mutant polynucleotides encode polypeptides that comprise mutations in the EAR motifs.
