    • 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.

    • The present invention provides chimeric genes that comprise a first promoter recognized by a DNA-dependent RNA polymerase different from a eukaryotic RNA polymerase II; a DNA region encoding a chimeric RNA which comprises a 5'UTR, an AU-rich heterologous coding sequence, a 3'UTR; and optionally a terminator sequence recognized by said RNA polymerase, wherein the first promoter and the DNA region encoding the chimeric RNA are operably linked such that upon transcription by the RNA polymerase an uncapped RNA species is produced which comprises a first translation enhancing sequence derived from the 5' region of genomic or subgenomic RNA of a positive stranded RNA plant virus; a heterologous RNA coding sequence encoding a polypeptide or protein of interest, preferably from an AT-rich gene; and a second translation enhancing sequence derived from the 3' region of genomic or subgenomic RNA of a positive-stranded RNA plant virus, wherein the uncapped RNA species is capable of being translated in the cytoplasm of a plant cell to produce the protein or polypeptide. Also provided in the invention are plant cells and plants comprising these chimeric genes, integrated in their nuclear DNA, whereby the plant cell produces the RNA polymerases corresponding to the used promoters and terminators. Further the invention provides a process for producing a plant expressing a protein or polypeptide encoded by a heterologous gene which comprises the steps of transforming the nuclear genome of a plant cell with the above-mentioned chimeric genes; and regenerating a transformed plant from the transformed cell.
