the invention relates to a nucleinic acid molecule coding for a protein acting as a subunit CHLD of plant Mg-chelatases, or for an active fragment thereof; a protein acting as a subunit CHLD, or an active frament thereof, preferably a recombinant protein; a method for determining the interaction of plant Mgchelatase subunits, whereby a host cell with a DNA sequence in line with one or more of claims 1-3 and with at least one DNA sequence coding for another Mgchelatase subunit is converted in such a way that the interaction of the Mgchelatase gene products triggers a directly or indirectly measurable quality or quantity signal, preferably by activating a marker gene; transgenic plants, transgenic plant cells, transgenic plant seeds and transgenic reproduction material, containing a nucleinic acid molecule such as mentioned above.
