Abstract: The present invention relates to the field of insect pests control, using methods and compositions which comprise of alpha-amylase analogous mutant inhibitors (?AIs). More specifically, the invention provides new ?AIs analogous mutant molecules for controlling insect pests, in particular boll weevils (Anthonomus grandis), partially or totally presenting reduction of the amylolytic activity of the digestive enzymes in the intestinal lumen of the insect. Other aspects of the invention include gene constructs containing the nucleic acid molecules that code for the alpha-amylase inhibitors, heterologous expression methods of the new molecules in the active form, and the use of these molecules for controlling insect pests. The invention also provides analogous synthetic genes optimized for their transformation and expression in plants.

Abstract: The present application relates generically to compositions used for controlling agricultural pests and, in a particular, to compositions usable for combating nematodes. The application presents a feasible alternative to the use of nematotoxic compounds that are harmful to the environment and that may damage human health. This alternative includes a nematotoxic composition for controlling nematodes that may be used on plants, parts of plants and on the soil. The respective technology results from unexpected results achieved from experiments carried out with extracts of the plant Canavalia ensiformis, resulting in an unheard-of nematotoxic composition comprising a specific combination of substances that are naturally found in the extract and that act synergistically.

Abstract: The present invention belongs to an insecticide compound derived from a strain of Bacillus thuringiensis and refers to the field of controlling plant pests, particularly to the control of the boll weevil—Anthonomus grandis. More specifically, the object of the invention refers to a new gene for the new delta-endotoxin designated Cry8Ha and to the cloning and expression of the gene that encodes for the protein Cry8Ha in Escherichia coli. There is provided the nucleotide sequence and encoding protein of the new delta-endotoxin, recombinant vectors and host cells. There is also provided processes and means for recombinant production and the use of the new delta-endotoxin for application in the control of the boll weevil. Additionally, the invention also provides an optimized synthetic gene for expression in cotton plants. Using the gene described herein, it is possible to transform plants based on techniques known by specialists in the art, for the expression of the endotoxin active against the boll weevil.

Abstract: The present Invention relates to regulatory sequences of polynucleotides isolated from cotton plants capable of initiating and activating the transcription of polynucleotides, and the use of these regulatory sequences for modifying the transcription of endogenous and/or heterologous polynculeotides and the production of polypeptides.

Abstract: A polynucleotide isolated from cotton plants capable of initiating transcription and with sequence identity to SEQ ID No.1 is provided. In some aspects, the polynucleotide has sequence identity to SEQ ID No. 1 of at least 40%, is the reverse complement or the reverse of such sequences. In some aspects, the polynucleotide is linked to expression enhancers or sequences of interest. In some embodiments, a recombinant vector comprises the polynucleotide. In some aspects, the recombinant vector comprises enhancers, termination sequences, or sequences of interest. In some embodiments a transformed cell, plant, plant part, or propagulum comprise the polynucleotide.
