Abstract
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.
