Sorry, this information has not been prepared for the MADS box gene homepage yet. But you can see most of the information which will appear here already as a part of Günter Theissen's group homepage.
Additionally, you may get an idea at least of the complexity of MADS box gene evolution by checking out the MADS phylogeny page of this site.
