    • The invention pertains to a process for producing a determined polypeptide of interest or repeats thereof in a seed forming plant. It comprises: cultivating plants obtained from regenerated plant cells or from seeds of plants obtained from said regenerated plant cells over one or several generations, whose genetic patrimony, replicable with said plants, comprises a precursor-coding nucleic acid sequence encoding the precursor of a plant storage protein and placed under the control of a seed promoter, said precursor-coding nucleic acid being modified in a non-essential region of its relevant sequence which encodes the mature storage protein or a sub-unit thereof with a nucleic acid insert in appropriate reading phase relationship with the surrounding part of said relevant sequence, said insert including a determined segment encoding a heterologous determined polypeptide of interest or repeats thereof linked to each other and downstream and upstream thereof to the remainder parts of said relevant sequence through codons encoding aminoacid(s) which define selectively cleavable border sites surrounding the peptide of interest in the hybrid storage protein encoded by the so-modified relevant sequence of said precursor-coding nucleic acid; recovering the seeds of the cultivated plants and extracting the hybrid storage proteins contained therein; cleaving out the peptide of interest from said hybrid storage protein, purifying and recovering the peptide of interest. The polypeptide of interest may be a biologically active protein and/or a labeled protein.

    • Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis ipsilon, against Pyralidae such as Ostrinia nubilalis, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene. The crystal proteins contain protoxins, which can yield a toxin as trypsin-digestion product. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that encodes its respective toxin, is resistant to Lepidoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Lepidoptera.
    • 四种新型苏云金芽孢杆菌菌株,其保藏在BCCM-LMG,保藏号为。 LMG P-12592,LMG P-12593,LMG P-12594和LMG P-13493在孢子形成过程中产生对鳞翅目有毒的新的晶体蛋白质,更特别地针对夜蛾科(Spodoptera spp)等等。 和Agrotis ipsilon,针对鞭毛虫如鸵鸟(Ostrinia nubilalis),以及针对pon科(Yponomeutidae)如小菜蛾(Plutella xylostella),并且由新基因编码。 晶体蛋白含有原毒素,其可以产生作为胰蛋白酶消化产物的毒素。 一种植物,其基因组用来自任一种菌株并编码其各自毒素的DNA序列转化,对鳞翅目具有抗性。 每种菌株本身或其晶体,晶体蛋白质,原毒素或毒素都可用作杀虫鳞虫的杀虫组合物中的活性成分。
