In this respect, it is relevant to note that plant species CROSS-REFERENCE TO RELATED which accumulate large amounts of diterpenes are equipped APPLICATION with specialised organs, the Secreting trichomes, dedicated to the synthesis thereof. Tobacco and in particular Nicotiana This application is the U.S. national stage application of Sylvestris, are a typical example where there is an abundant International Patent Application No. PCT/FR2006/000188, GGPP pool in the trichomes in order to ensure a high flow of filed Jan. 27, 2006, the disclosure of which is hereby incor cembranoid synthesis, and hence the high accumulation porated by reference in its entirety, including all figures, 10 thereof at the surface of the aerial parts. tables and amino acid or nucleic acid sequences. The steps leading to the biosynthesis of CBT-diol in tobacco have been partially elucidated and can be broken FIELD OF THE INVENTION down into two different parts: biosynthesis of the universal precursor of all diterpenes, The invention relates to a method for producing com 15 geranylgeranyl pyrophosphate (GGPP), via the pounds of interest in plants and to genetically modified plants so-called “Rohmer pathway (Rohmer et al., 1996), prepared for use in said method. The invention also relates to takes place in the chloroplast. genetically modified plants enabling an enhanced efficiency biosynthesis of CBT-diol from GGPP. Wang and Wagner of transformation.

They The first cyclization step would be carried out by an take various forms and are classified into two main categories. 25 enzyme from a large family of enzymes known as terpene The first includes hairs, or non-secreting trichomes, unicel synthases (Bohlmann et al., 1998). The diterpene synthase of lular or multicellular. They do not secrete substances to the tobacco would use GGPP as substrate to form CBT-ol. The exterior, or at least not in appreciable amounts. The second second step whereby CBT-diol is produced from CBT-ol is a group comprises all trichomes described as secreting or glan hydroxylation catalyzed by an enzyme from the cytochrome dular, which have an increased capacity to synthesize and 30 P450 family.
