Abstract: This invention relates to a method for obtaining castor-oil plants deprived of the ricin/RCA protein, through the insertion of gene constructs into plant cells, particularly castor-oil plant ones, with the consequent production of ricin/RCA-free castor-oil plant seeds. An aspect of the invention consists in providing castor-oil plants and parts thereof containing said gene construct. The method disclosed herein appeared to be efficient to the generation of castor-oil plants deprived of ricin protein or showing low expression levels of this protein, thus allowing the use of the seed thereof to the production of detoxified cakes, both for animal nutrition and for fertilizers, not to mention its possible production in countries that set restrictions to this substance, due to ricin toxicity. Therefore, this invention also provides a method and a kit to the identification of transformed plants containing the gene constructs disclosed herein.

Abstract: The present invention relates to a new promoter of the expression of genes in plants. More specifically, the invention relates to regulatory sequences of polynucleotides that are isolated from soy plants and can initiate and activate polynucleotide transcription, and to the use of these regulatory sequences to modify the transcription of endogenous and/or heterologous polynucleotides and to produce polypeptides. The invention further describes DNA constructs that contain the promoter of the gene of the supposed flavonol-sulfotransferase protein in soy plants, which promoter is functionally linked to a heterologous and/or endogenous gene. Moreover, the invention relates to the use of these constructs in the form of expression cassettes, expression vectors, recombinant vectors and in plants, plant cells or transgenic protoplasts.

Abstract: The Present invention relates to molecules isolated from the nucleic acid that encodes spider web proteins or fragments of these or other derivatives of these. The invention also refers to a chimerical gene and an expression vector containing molecules isolated from the nucleic acid that codes for proteins related to the webs of Nephilengys, cruentata, Avicularia juruensis and Parawixia bistriata spiders. Another embodiment of the present invention are transformed cells containing a chimerical gene or an expression vector of the present invention. Yet another embodiment of the present invention relates to a method for obtaining genetically modified organisms containing inventive chimerical genes or expression vectors and a method for obtaining recombinant proteins from the silks of Nephilengys, cruentata, Avicularia juruensis and Parawixia bistriata spiders. Finally, the invention describes products, such as biofilaments and compositions, using the recombinant proteins of the present invention.

Abstract: The present invention relates to the control of pest infestation by inhibiting or reducing the expression of genes of the family of chitin synthase and of vitellogenin, as well as through the expression of the toxin Cry8ka5. The invention further provides method and compositions for controlling pests, by feeding the pest with one or more double-stranded RNA molecules provided by the present invention, as well as double-stranded RNA molecule provided by the present invention, as well as through the action of the toxin Cry8ka5 on the target insect. The invention further describes a method of obtaining transgenic plants that express double-stranded RNA molecules and the toxin protein Cry8ka5. The present invention is preferably used for cotton plants.

Abstract: The present invention relates to a polynucleotide sequence capable of efficiently modifying the expression of one or more genes of interest in leaves, in particular in plants of the Glycine genus, and the tools to obtain genetically-modified plants using this sequence and the use thereof. The usage possibilities of the invention are broad, prominently, the creation of new plant varieties resistant to diseases and leaf-attacking pests, expression of transgenes that increase the photosynthetic efficiency of the plant, guiding the expression of proteins of interest as antibodies and drugs that may easily be isolated from leaves.
