Abstract: A method for isolating a fungus-responsive promoter comprising the steps of:(i) identifying a promoter sequence in the genomic DNA of a plant using a promoter-effective portion of the promoter of the gene of SEQ ID No. 1 as a hybridization probe, and(ii) isolating said fungus-responsive promoter.

Abstract: The present invention is directed to DNA sequences that from Cuphea lanceolata code for a middle chain-specific acyl-?ACP!-thioesterase, and alleles and derivatives of these DNA sequences. The present invention also is directed to process for producing plants, parts of plants or plant products that contain these DNA sequences, alleles or derivative of these DNA sequences, where the plants, parts of plants or plant products produce fatty acids of middle chain length.

Abstract: Fungus-responsive chimaeric genes are used in the production of transgenic plants which can produce plant cells surrounding the fungus infection that become capable of killing, disabling or repelling the fungus or that are themselves killed or rendered unsuitable for the fungus to feed upon, thereby preventing the spread of the fungus infection.

Abstract: A method and an apparatus for stacking sheets conveyed continuously at a stacking point. With the assistance of a separating member (6, 7), which can be introduced into a natural gap between the upper side of a stack and the sheets conveyed in an overlapping manner, in the conveying direction from the rear side of the stack (4), two gaps are created one after the other, into which clamping jaws (9, 10) arranged at different heights can be inserted. By clamping the wad of sheets (13) located between the inserted clamping jaws (9, 10), with simultaneous lowering of the stack of sheets (4), a larger gap is created below the wad of sheets (10), into which an auxiliary stacking platform (11), located directly below the lower clamping jaw (9), can be introduced. Since the sheets of the wad of sheets are held by the clamping jaws (9, 10), there is no danger that sheets may slide due to the formation of a "bow wave" at the front edge of the auxiliary stacking platform (11), as it is inserted.

Abstract: In a stack changing apparatus for sheet ejecting machines having a drop table vertically movable within a first frame structure, the drop table having a pallet to be placed thereon for receiving stacks; and a second vertical frame structure provided behind the first vertical frame structure having a carriage which is movable vertically and parallel to the drop table and, provided with pallet transport elements, is also horizontally movable between the second and the first frame structure, the improvement wherein one of two stacking platforms is alternatively used as the drop table, the platforms being selectively movable to one of the two sides of the first vertical frame structure and their stacking surfaces being below the level of the floor, the apparatus being further provided with an auxiliary skid for each stacking platform, the height of the auxiliary skid being such that when on a stacking platform the top of the skid is substantially level with the floor, each auxiliary skid having take-up elements f
