The invention relates to a DNA fragment containing a determined gene, the expression of which inhibits the antibiotic and herbicidal effects of Bialaphos and related products. It also relates to recombinant vectors, containing such DNA fragment, which enable this protective gene to be introduced and expressed into cells and plant cells.

Genetically engineered plant cells and plants exhibiting resistance to glutamine synthetase inhibitors, DNA fragments and recombinants for use in the production of said cells and plants

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 stamen cells of the plant. The foreign DNA sequence also optionally encodes a marker.

Plants with modified stamen cells

A plant, the nuclear genome of which is transformed with a foreign DNA sequence encoding a protein or polypeptide which disrupts the metabolism, functioning and/or development of stamen cells of the plant, said foreign DNA under the control of a stamen-specific promoter. The foreign DNA sequence also optionally encodes a marker.

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.

Transformation vectors allowing expression of truncated BT2 endotoxins

A plant, the nuclear genome of which is transformed with a foreign DNA sequence encoding a product which neutralizes the activity of another product which disrupts the metabolism, functioning and/or development selectively of the plant's flower cells, particularly reproductive organ cells, or seed cells or embryo cells. The foreign DNA sequence also optionally encodes a marker.

Plants with modified flowers

Use of anthocyanin genes to maintain male sterile plants

Transgenic plants that have, stably integrated into their nuclear genome, a maintainer gene comprising a fertility-restorer gene and a pollen-lethality gene. The plants can be used to maintain a homogenous population of male-sterile plants.

Maintenance of male-sterile plants

This invention is directed to a method to maintain male sterility in corn by the genetic linkage via genetic engineering of a homozygous male-fertility gene with a color linked restorer and plant comprising said genes. Color genes disclosed as useful in this invention include those involved in anthocyanin biosynthesis, which in corn are under the control of as many as 20 or more genes. In particular, the use of the anthocyanin color genes R, B and C1, and specific regulatory elements sequences are taught.

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.
