摘要:
The invention relates to nucleic acid molecules which code for enzymes and which are involved in the synthesis of starch in plants. These enzymes concern isoamylases derived from wheat. The invention also relates to vectors and host cells which contain the described nucleic acid molecules, especially transformed plant cells and plants which can be regenerated therefrom, which exhibit an increased or reduced activity of the inventive isoamylases.
摘要:
The invention relates to a method for combating pests in genetically modified cotton plants. The plants contain a gene derived from Bacillus thuringiensis. This gene codes for and expresses a protein with an insecticidal effect. The inventive method is characterised in that an insecticidally effective quantity of one or more specified compounds is applied to the plants, to their seeds or reproductive material and/or to their growing area. The inventive method enables a reduced quantity of pesticides to be used, said pesticides working synergistically with the transgenetic plants, and increases and diversifies the efficiency of the transgenetic plants. As a result, the invention presents both economic and ecological advantages.
摘要:
The invention relates to substituted piperidines of formula (I), wherein R1 represents H, halogen, alkyl, alkyl halide or cycloalkyl; R?2 and R3¿ have the meaning given in the description; A represents CH or N; X represents NH, O or S(O)¿q?, q being equal to 0, 1 or 2; Y and Z represent O, S or optionally substituted imino; m and n are equal to 1, 2, 3, 4, or 5; R?4 and R4'¿ represent H, alkyl, alkyl halide, halogen or alkoxy; R5 represents one or more of the following optionally substituted groups: alkyl, alkenyl, alkynyl, aryl or heterocyclyl, one or more C-units which can be substituted with CO or heteroatom-units. The invention also relates to a method for preparing said compounds, agents containing them and their use as pesticides and fungicides.
摘要:
A method for preparing granules containing one or more active principles, wherein the active principle(s) is(are) dissolved in a solvent, the resulting solution is absorbed onto a carrier, water is optionally added to the resulting product, and the product is dried and granulated. The resulting granules are also disclosed.
摘要:
The invention relates to a herbicidal agent comprising A) one or several sulphonylureas of general formula (I) and/or their salts and B) one or several plant oils.
摘要:
There is described a process for the preparation of compounds of formula I in which
R is hydrogen, optionally substituted alkyl, optionally substituted alkenyl optionally substituted cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl, and R 1 and R 2 are hydrogen, an organic radical or together with the ring to which they are attached, form an optionally substituted ring, which may contain one or more hetero atoms, which comprises reacting a compound of formula II with a compound of formula III in which the ring Q is an optionally substituted heteroaromatic ring, which optionally comprises one or more further hetero atoms and to which is optionally fused an optionally substituted ring.
摘要:
The invention relates to nucleic acid molecules which code for enzymes which are involved in the synthesis of starch in plants. Said enzymes are novel isoforms of starch synthetase. Vectors for the production of transgenic plant cells and plants which synthesize modified starch are also disclosed. A method for the production of said transgenic plant cells and plants is additionally disclosed as well as a method for the production of modified starch.
摘要:
Nucleic acid molecules are described encoding an R1-protein from wheat and methods and recombinant DNA molecules for the production of transgenic plant cells and plants synthesizing a modified starch. Additionally, the plant cells and plants resulting from those methods as well as the starch obtainable therefrom are described.
摘要:
Plasmids are described having DNA sequences that after insertion into the genome of the plants cause changes in the carbohydrate concentration and the carbohydrate composition in regenerated plants. These changes can be obtained from a sequence of a branching enzyme that is located on these plasmids. This branching enzyme alters the amylose/amylopectin ratio in starch of the plants, especially in commercially used plants.
