The present invention relates to a nucleic acid molecule which encodes a protein with the function of a plant Mg chelatase subunit CHLD or an active fragment thereof; a protein which has the function of a plant Mg chelatase subunit CHLD or an active fragment thereof, preferably a recombinant protein; a method of determining the interaction of plant Mg chelatase subunits, in which a host cell is transformed with a DNA sequence as claimed in one or more of claims 1 to 3 and at least with one DNA sequence encoding a further subunit of Mg chelatase in such a manner that the interaction of the Mg chelatase gene products leads to a directly or indirectly, qualitatively or quantitatively measurable signal, preferably by activating a marker gene, and transgenic plants, transgenic plant cells, transgenic plant organs, transgenic plant seeds, transgenic propagation material comprising an abovementioned nucleic acid molecule.

The present invention relates to new nucleic acid sequences, which code for a geranylgeranyl reductase, a method for producing new plants which contain the new DNA sequence and the content of tocopherol and/or chlorophyll of which is altered in comparison to wild-type plants, these new plants, parts and products thereof and plant cells as well as the use of the DNA sequences for the manipulation of tocopherol, chlorophyll and/or vitamin K content in transgenic plants, parts and products thereof and plant cells.
