    Abstract: A process for producing a thermoformable and/or -embossable fiber/polymer composite using a fibrous lignocellulosic substrate S and a polymer P, which contains i) homogeneously mixing the substrate S and the polymer P, then ii) converting the substrate S/polymer P mixture to a fiber web, and then iii) compacting the resultant fiber web at a temperature not less than the glass transition temperature of the polymer P [TgP] to give a thermoformable and/or -embossable fiber/polymer composite, wherein a) the substrate S comprises acetylated lignocellulosic fibers, and b) the polymer P is thermoplastic and has a TgP≥20° C. The invention relates to a fiber/polymer molding obtainable by the process and a component in motor vehicle construction, in built structures and in furniture which contains the fiber/polymer molding.

    Abstract: The present invention refers to a method for controlling undesired vegetation at a plant cultivation site, the method comprising the steps of: providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a wild-type hydroxyphenyl pyruvate dioxygenase or a mutated hydroxyphenyl pyruvate dioxygenase (mut-HPPD) which is resistant or tolerant to a N-heterocyclyl-arylcarboxamide and/or a nucleotide sequence encoding a wild-type homogentisate solanesyl transferase or a mutated homogentisate solanesyl transferase (mut-HST) which is resistant or tolerant to a N-heterocyclyl-arylcarboxamide, and applying to said site an effective amount of said herbicide. The invention further refers to a method of identifying a nucleotide sequence encoding a mut-HPPD which is resistant or tolerant to a N-heterocyclyl-arylcarboxamide, as well as transgenic plants having increased resistance or tolerance to a N-heterocyclyl-arylcarboxamide as compared to a wild-type variety of the plant cell.
