The present invention provides isolated HaHB11 polypeptides and nucleic acids encoding the same. Also provided are methods of introducing a nucleic acid encoding HaHB11 polypeptides into a plant cell, plant part or plant, e.g., to increase tolerance to abiotic stress, to delay development and/or prolong the life span of a plant, and/or to increase yield from the plant. The invention also provides nucleic acids comprising HaHB11 promoter sequences and methods for expressing a nucleotide sequence of interest operably associated with the HaHB11 promoters of the invention in a plant cell, plant part, or plant. Also provided are transformed plants, plant tissues, plant cells and plant seed comprising the nucleic acids, expression cassettes and vectors of the invention.

HaHB11 provides improved plant yield and tolerance to abiotic stress

A polynucleotide having at least 80% sequence identity with the full-length nucleotide sequence of SEQ ID NO: 1 and substantially identical polynucleotides; an isolated polypeptide having at least 80% sequence identity with the full-length amino acid sequence of SEQ ID NO: 2 and substantially identical polypeptides; and polynucleotides encoding the Ha WRKY76 polypeptide and substantially identical polypeptides are described. Also described are vectors and recombinant expression cassettes containing the c DNA polynucleotide, a polynucleotide encoding the Ha WRKY76 polypeptide, or substantially identical polynucleotides. Transgenic plants containing such expression cassettes, related methods and uses are also provided.

HAHB11 provides improved plant yield and tolerance to abiotic stress

A new transcription factor coding gene induced by water deficit or abscisic acid of, having a homeodomain associated to a leucine zipper, was characterized. The transcription factor is useful to be cloned in DNA constructions for transforming host cells and plants. The transgenic plants comprising the transcription factor gene are tolerant and resistant to harmful environmental conditions such as water stress and high salinity. A nucleic acid promoting sequence is also provided wherein the sequence is induced by water deficit or abscisic acid. Constructions, host cells and transgenic plants that comprise the transcription factor gene are provided.

[object Object]

The present invention refers to a gene fromencoding a transcription factor that comprises a homeodomain associated with a leucine zipper. This gene is named Hahb-10. The transcription factor Hahb-10 can be used in DNA constructs to transform host cells and plants. Transgenic plants that overexpress this transcription factor are more tolerant to herbicides, and have a shorter life cycle.

An isolated DNA molecule for enhancing gene expression of a coding sequence, fragment, genetic variant, cassette, vector, cell, plant and seed containing said molecule, wherein the molecule comprises introns for induce an increase in the expression level of a transgene, useful in DNA constructions for transforming plant cells, wherein the cell or plant has a construction containing one of these introns under control of a promoter and upstream of a coding sequence stably integrated in its genome displaying higher expression levels as compared to non-transformed cells or plants, or cells or plants transformed with constructions that lack the inventive intron, wherein the sequences of 5'-non-coding sequences of the genes mentioned above also comprise promoters and exonic sequences in DNA constructions displaying synergism with the effect produced by the intron, and wherein the 5&#x2032;-non-coding sequences of COX5-c genes lacking said intron promote tissue-specific expression in pollen when they are comprised in DNA constructions for plant transformation.
