The chloroplast vesiculation (CV) gene encodes a protein associated with stress-induced chloroplast degradation. Inhibiting expression or activity of the protein inhibits or delays stress-induced chloroplast degradation and confers tolerance to a variety of stress conditions. Alternatively, enhancing CV expression or activity promotes chloroplast degradation and enhances nutrient assimilation in desired sink tissues, such as young leaves, fruit, or seeds.

Plant tolerance to stress through the control of chloroplast stability

The present invention relates to the development of drought-resistant plants. This invention is directed to the preparation of transgenic plants that express a protein involved in cytokinin synthesis under the control of a senescence-inducible promoter. More specifically, this invention relates to the preparation of transgenic plants that express an isopentenyl transferase under the control of a senescence-associated receptor kinase (SARK) promoter.

Drought-resistant plants

The present invention is generally related to plant genetic engineering. In particular, the invention is directed to nucleic acids and methods for conferring salt tolerance on plants and other organisms.

Transporters and their uses

The subject invention includes non-naturally occurring salt tolerant plants that accumulate sodium in their tissues substantially in the vacuole. The present invention also includes methods of making such non-naturally occurring plants. One preferred method is generating a transgenic plant that has an ectopically expressed NHX related gene product.

High salt plants and uses for bioremediation

The invention is isolated nucleic acid molecules encoding Na/Hexchanger polypeptides with at least 95% homology to that offor extrusion of monovalent cations from the cytosol of cells to provide the cell with increased salt tolerance. Crop species transformed with the nucleic acid molecule are capable of surviving in soil with high salt levels that would normally inhibit growth of the crop species.
