  • Patent number: 8283521
    Abstract: A new transcription factor coding gene induced by water deficit or abscisic acid of Helianthus annuus, 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.

  • Publication number: 20120185964
    Abstract: We characterise a plant transcription factor and disclose its use in modifying plant responses to stress conditions, including freezing, drought, salinity and pathogen invasion. Microarray analyses were performed indicating that such tolerance occurs via the increase of antifreeze proteins localized in the cellular apoplast which inhibit the growth of large extracellular ice crystals. We also disclose the use of such proteins.

  • Patent number: 7674954
    Abstract: The present invention refers to a gene from Helianthus annuus encoding 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.

  • Patent number: 7598368
    Abstract: 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?-non-coding sequences of COX5-c genes lacking said intron promote tissue-specific expression in pollen when they are comprised in DNA c
