Definitions

  • the invention relates to isolated polynucleotides and the proteins encoded by them, and their use for combating hawthorn beetles (Scarabaeidae).
  • the invention also relates to a method for producing these proteins
  • Greenhorn beetles such as the field cockchafer (Melolontha melolontha) or the forest cockchafer (Melolontha hippocastan ⁇ ) and especially their larvae (grubs) can cause great damage in agricultural and forestry crops. Since their control by chemical insecticides is difficult and environmentally harmful, efforts are being made to an increasing extent to control the multiplication and spread of these insects using biological agents. For example, EP 633936 A1 describes a method in which vegetative cells, spores or protein crystals of certain strains of Bacillus thurmgiensis are used to control hawthorn beetles. The effectiveness of this method is, however, effective not satisfying
  • B. popilliae is the causative agent of the so-called Milky Disease in larvae of cockchafer and other hawthorn beetles.
  • the larvae infected with the Bacillus have high concentrations of vegetative cells and sporangia of B. popilliae in their hamolymph, which cause a milky white discoloration of the grub
  • the bacterium B. popilliae is characterized, among other things, by the fact that it does not form catalase, most isolates are resistant to the antibiotic vancomycin and, during sporulation, form a conspicuous protein crystal, which is arranged inside the spindle-shaped sporangium next to the actual spore in its capacity as a pathogen B. popilliae has a high specificity for scarabaeids.
  • the B. popilliae subspecies isolated from different scarabaeid species differ in part considerably in their growth properties, the composition of the protein crystal and their plasmids
  • Bafer larvae are infected with B. popilliae by ingestion of the sp ⁇ rangia in the larvae, the spores germinate, and the vegetative bacterial cells penetrate through the intestinal epithelium and the basement membrane into the hamolymph and then multiply there over the next three to four weeks sporulate the B. popilliae cells, which ultimately leads to the death of the kafer larva
  • B. popilliae forms predominantly vegetative cells and only exceptionally spores under in vitro conditions.
  • WO 87 05 928 describes a method for obtaining the spores in vitro, in which the vegetative cells of B.
  • popilliae in one defined medium can be cultivated and finally stimulated to sporulation by adding a certain adjuvant, but even with this method only a sporulation rate of about 80% is achieved.
  • a considerable amount of equipment and personnel is consequently required and financial effort required, which makes this method economically unprofitable and therefore unsuitable for practice It is therefore an object of the present invention to provide biological agents for controlling scarabids which allow satisfactory control of these pests and which are technically simple and inexpensive to produce even in large quantities
  • polynucleotides which encode proteins which are identical or at least related to the crystal proteins which are characteristic of Bacillus popilliae, and which fully or partially or by way of substitution represent the nucleotide sequence shown in the sequence listing SEQ ID NO: 1 , Deletion, insertion and / or inversion of a nucleotide sequence derived therefrom or a nucleotide sequence which hybridizes wholly or partly therewith.
  • polynucleotides according to the invention themselves can either be obtained from a natural source or can also be produced synthetically or semi-synthetically.
  • telomeres are preferably present as a component of a recombinant DNA vector molecule which has the ability to express the crystal protein or protein crystal characteristic of Bacillus popilliae or a protein related thereto in a prokaryotic or eukaryotic cell.
  • This vector molecule has the advantage, inter alia, that it can be introduced into any cell, for example a commercially available, easy-to-cultivate bacterial culture of E. coli or Bacillus thuringiensis, subjected to a promoter which is already present in or incorporated into the cell and can be both replicated and expressed as Vector molecules are particularly suitable for plasmids derived from gram-positive bacteria
  • the use of transformed host cells which contain a polynucleotide according to the invention which is coupled to a promoter which is naturally contained in the host cell or as a result of a recombination.
  • Polynucleotide (s) are introduced into the host organism, ie into a microorganism, a virus, a protozoon, a plant cell or the like, for example by transformation, transduction or conjugation, integrated into the genetic material of these cells or viruses and brought to expression
  • Bacillus thunngiensis for example Bacillus thunngiensis subsp kurstaki, have proven to be particularly suitable host cells. Bacillus thunngiensis has been very well studied and it is comparatively easy to produce the crystal protein of B. popilliae in large amounts in this system
  • the protein (s) according to the invention can be used alone or in combination with at least one other substance as a biological insecticide for combating scarabids, ie for inhibiting feeding and / or killing adult and / or larval scarabids, in particular Melolontha - Types and species closely related to them.
  • substance here includes chemical and biological materials including microorganisms.
  • pathogens such as viruses, rickettsia, bacteria, fungi, microsporidia and others can result in an advantageous increase in the crystal toxin effect
  • the proteins according to the invention are used together with spores of Bacillus popilliae and / or Bacillus thunngiensis.
  • Bacillus sphaericus spores are also well suited
  • Another, also very advantageous variant provides that the proteins according to the invention are used in combination with cytolysing proteins and / or receptor proteins for the intestinal epithelium of scarabaeids, preferably in the form of fusion proteins
  • proteins according to the invention are used in combination with fungal spores
  • one or more of the polynucleotides according to the invention infiltrates (transforms) into a microorganism (e.g. a bacterium, virus, fungus or protozoan) or into a cell of an animal or plant cell culture Control and control of a promoter contained in this microorganism or in this cell, naturally or as a result of a recombination, preferably subject to regulation and expression.

  • the polynucleotide (s) is introduced into a bacterium of the Bacillus thunngiensis type
  • the invention also encompasses the possibility of transferring polynucleotides according to the invention into plants or parts of plants in order to protect them against scarab acid seizure.
  • it also includes the use of polynucleotides according to the invention for the production of transgenic plants with the property of a knee protein in all or some plant tissues to synthesize, which is similar or similar to the crystal protein characteristic of Bacillus popilliae, and which inhibits the feeding and / or killing of larval and / or adult Scarabaeids, in particular Melolontha species and closely related to them Species is suitable and / or also for inactivating and / or killing such soil organisms which damage plants and / or fungi and / or transmit diseases
  • a method for the production of plants or plant tissues or plant propagation material with recombined genetic material, which comprises a heterologous polynucleotide according to the invention, the expression of which leads to a protein which is similar or similar to the crystal protein which occurs naturally and characteristically in Bacillus popilliae.

  • Example 1 The invention is explained in more detail below on the basis of exemplary embodiments Example 1:

  • Corresponding oligonucleotides are synthesized for partial sequences from the two end regions of the protein in order to serve in a polymerase chain reaction (PCR) as a primer for the synthesis of a DNA probe for the crystal protein gene.
  • the PCR is carried out using the total DNA from Bacillus popilliae subsp melolonthae
  • the isolated crystal protein can also first be split into short fragments, then the amino acid sequence of some of these fragments determined and, by comparison with the amino acid sequence of the Cry II A protein from Bacillus thunngiensis known in the prior art, two fragments which are presumably from the two end regions selected of the protein.
