An isolated DNA molecule is provided coding for a polypeptide of the 11-12 transmembrane domain transporter family having a Mg /H or Zn /H exchange activity, herein designated MHX. The genomic MHX DNA was isolated from cv. C-24. Transgenic plants transformed with said DNA and expressing MHX are shown to have a lower content of sodium as compared with corresponding wild-type plants or a higher dry matter weight upon growth in calcium-rich media as compared with corresponding wild-type plants. These transgenic plants are tolerant to stress conditions, particularly high salinity and calcium-rich media, e.g. saline and calcareous soils.

DNA coding for a Mg2&plus;/H&plus; or Zn2&plus;/H&plus; exchanger and transgenic plants expressing same

Chimaeric DNA sequence which encodes: 1) a transmit peptide of a cytoplasmic precursor of a chloroplast protein or polypeptide of a plant and 2) a protein or polypeptide that is heterologous to the transit peptide. The chimaeric DNA sequence can be used as a vector for transforming a plant cell so that a chimaeric precursor of the heterologous protein or polypeptide is produced in the cytoplasm of the cell and the chimaeric precursor then transports the heterologous protein or polypeptide in vivo into a chloroplast of the cell.

Chimaeric gene coding for a transit peptide and a heterologous

Novel transformation vectors containing novel chimeric genes allow the introduction of exogenous DNA fragments coding for truncated Bacillus thuringiensis Bt2 polypeptide toxins and expression of the chimeric gene in plant cells and their progeny after Integration into the plant cell genome. Transformed plant cells and their progeny exhibit stably inherited polypeptide toxin expression useful for protecting said plant cells and their progeny against Lepidopteron insect pests and in controlling said insect pests.

Chimaeric DNA sequence which encodes: 1) a transit peptide of a cytoplasmic precursor of a chloroplast protein or polypeptide of a plant and 2) a protein or polypeptide that is heterologous to the transit peptide. The chimaeric DNA sequence can be used as a vector for transforming a plant cell so that a chimaeric precursor of the heterologous protein or polypeptide is produced in the cytoplasm of the cell and the chimaeric precursor then transports the heterologous protein or polypeptide in vivo into a chloroplast of the cell.

Chimaeric gene coding for a transit peptide and a heterologous peptide

Disclosed is substantially pure DNA encoding a crucifer ACC synthase polypeptide; a promoter functional in immature plant tissues which is capable of ethylene induction; and methods of using such promoters to express recombinant proteins or RNA and to regulate ethylene-inducible events of a plant, e.g., fruit ripening or senescence, especially during early stages of plant development.

Crucifer ACC synthase and uses thereof

Novel transformation vectors containing novel chimeric genes allow the introduction of exogenous DNA fragments coding for polypeptide toxins produced by Bacillus thuringiensis or having substantial sequence homology to a gene coding for a polypeptide toxin as described herein and expression of the chimeric gene in plant cells and their progeny after integration into the plant cell genome. Transformed plant cells and their progeny exhibit stably inherited polypeptide toxin expression useful for protecting said plant cells and their progeny against certain insect pests and in controlling said insect pests.

Transformation vectors allowing expression of foreign polypeptide

A plant, the nuclear genome of which is transformed with a foreign DNA sequence encoding a product which selectively disrupts the metabolism, functioning and/or development of cells of the flowers, particularly one or more of their female organs, or the seeds or the embryos of the plant. The foreign DNA sequence also optionally encodes a marker.

Plants with modified flowers seeds or embryos

Endotoxins

The invention concerns female-sterile plants that comprise a foreign DNA incorporated in the nuclear genome of their cells. This foreign DNA first comprises a female-sterility DNA encoding a protein or polypeptide such as barnase which, when produced in the cells of the plant, kills or significantly disturbs the metabolism, functioning or development of the cells. The foreign DNA also comprises a first promoter which directs expression of the female-sterility DNA selectively in style cells, stigma cells or style-and stigma cells of the female reproductive organs of the plants. The first promoter does not direct detectable expression of the female sterility DNA in the ovule or in other parts of the plant so that the plant remains male-fertile. The female-sterility DNA is in the same transcriptional unit as and under the control of the first promoter.

Plants with genetic female sterility

A process for the production of plants with increased content of appropriate amino acids having high nutritional properties through the modification of plant genes encoding plant storage proteins, particularly the 2S albumins. Seed-forming plants susceptible to Agrobacterium transformation, the genome of which plants includes a recombinant DNA encoding a precursor of a modified 2S albumin, under the control of a promoter, are described, including the particular recombinant DNA.
