Abstract: The invention provides polynucleotides encoding plant prenyl protease polypeptides, vectors, host cells, and transgenic plant comprising the polynucleotides. The invention also provides methods of producing transgenic plants that have altered levels of prenyl protease polynucleotides and polypeptides, and transgenic plants that have increased tolerance to an environmental stress as compared to a wild type plant.

Abstract: The invention relates to methods of producing a desired phenotype in a plant by manipulation of gene expression within the plant. The method relates to means which inhibit the level of PK220 gene expression or activity, wherein a desired phenotype such as increased water use efficiency relative to a wild type control plant. The invention also relates to nucleic acid sequences and constructs useful such methods and methods of generating and isolating plants having decreased PK220 expression or activity.

Abstract: The invention relates to methods of producing a desired phenotype in a plant by manipulation of gene expression within the plant. The method relates to means which increase the level of expression of a MYB-subgroup14 polynucleotide or a MYB68 polypeptide. The method also relates to expression of a nucleic acid sequence encoding a MYB-subgroup14 or a MYB68 transcriptional factor. The methods are directed to elevating the levels of a MYB-subgroup14 or a MYB68 expression, wherein a desired phenotype such as reduced flower abortion and increased yield during heat stress is observed. The invention also relates to nucleic acid sequences useful in such methods.

Abstract: The invention relates to methods of producing a desired phenotype in a plant by manipulation of gene expression within the plant. The method relates to means which inhibit the level of FVE gene expression or activity, wherein a desired phenotype, such as increased biomass relative to a wild-type control plant, is achieved. The invention also relates to nucleic acid sequences useful for such methods.
