Abstract: This invention provides a process of amplification and/or expression of a sequence of interest in a cell by providing for generating within the cell at least one amplicon by trans-splicing between an RNA sequence designed for being capable of trans-splicing and a target RNA, whereby the amplicon is capable of amplifying in the cell and capable of expressing a sequence of interest.

Abstract: The present invention relates to enzymatic activity involved in isoprenoid biosynthesis as well as to inhibitors, notably herbicides, for enzymes in the biosynthesis of isoprenoids. More specifically, the present invention relates to screening methods for detecting such inhibitors, and to enzymatically active proteins for performing said methods as well as purified isolated DNA coding for such proteins. Moreover, the present invention relates to novel inhibitors detectable by said screening methods as well as compositions and processes for inhibiting the synthesis of isoprenoids and for controlling the growth of organisms based on said inhibitors. The invention relates also to the development of inhibitor-resistant plant enzymes and plants, plant tissues, plant seeds and plant cells.

Abstract: The present invention relates to production of alkaloids from poppy plants and in particular togenes encoding enzymes in the alkaloid pathway, to proteins encoded by the gens, to plants transformed or transfected with the genes and to methods of altering alkaloid content or blend of poppy plants.
