  • METHOD FOR DIRECTING NUCLEIC ACIDS TO PLASTIDS
    Publication number: 20090178161
    Abstract: The invention relates to nucleic acid sequences naturally imported into a plant cell plastid, and use thereof for directing an RNA sequence of interest to a plastid, which permits, in particular, the directed expression of a protein of interest in a plant cell plastid.

  • Screening method involving MGDG synthase
    Patent number: 6924092
    Abstract: The invention concerns a method for screening and selecting parasiticides (apicomplex phyllum parasites) and/or herbicides and the uses thereof. Said method consists in incubating a substance to be tested with a MGDG synthase and measuring the specific enzymatic activity, after said incubation. The invention also concerns the use of MGDG synthase or a plant isolated plastid membrane for selecting or screening the products inhibiting the activity of the MGDG synthase, capable of being used as active principles against apicomplex parasites and/or of being used as herbicides.
