摘要:
The present invention relates to novel gene sequences encoding insecticidal proteins produced by Bacillus thuringiensis strains. Particularly, new chimeric genes encoding a Cry1C, Cry1B or Cry1D protein are provided which are useful to protect plants from insect damage. Also included herein are plant cells or plants comprising such genes and methods of making or using them, as well as plant cells or plants comprising one of such chimeric gene and at least one other of such chimeric genes.
摘要:
The invention provides methods and means for the identification of genes involved in the determination of a plant trait or for the identification encoded by a nucleic acid comprising a determined nucleotide sequence. The invention also provides kits comprising viral RNA vectors derived from satellite viruses and corresponding helper viruses for the introduction of inhibitory RNA into plant cells and plants.
摘要:
The invention relates to the isolation of promoters from corn capable of directing transcription of an operably linked foreign DNA sequence preferentially, selectively or exclusively in the roots of plants, such as corn plants. The invention also relates to the use of chimeric genes for the preferential or selective expression of biologically active RNA of interest in the roots of plants, such as corn plants. Plants, such as corn plants, comprising corn root preferential or selective promoters operably linked to a foreign DNA sequence which, upon transcription, yield biologically active RNA preferentially or selectively in the roots of plants are also provided.

The present invention relates to novel DNA sequences encoding insecticidal Cry1 C proteins derived from Bacillus thuringiensis, and their use in plants to control insect pests. Also included herein are plant cells or plants comprising such genes and methods of making or using them, as well as plant cells or plants comprising a Cry1 C chimeric gene of the invention and at least one other chimeric gene, such as a chimeric gene encoding an insecticidal Cry1Ab protein, and methods of making or using such plant cells or plants.
摘要:
Methods and means are provided for the modification of the reactivity of plant secondary cell walls, particularly in cotton cell walls found in cotton fibers. This can be conveniently achieved by expressing a chimeric gene encoding a Saprolegnia monoica chitin synthase in cotton plants.
摘要:
The present invention relates to plants with a chimeric DNA molecule encoding a glyphosate tolerant EPSPS enzyme under the control of a plant constitutive promoter and a replacement histone intron 1, thereby conferring enhanced glyphosate tolerance to said plants.
摘要:
The present invention relates to materials and methods for the expression of a gene of interest selectively in cotton fibers. In particular, the invention provides an expression cassette for regulating fiber-selective expression in plants.
