Conservation of interactions among MADS-domain proteins. The different subfamilies are depicted by ovals; lines between the ovals indicate interactions in the different species as colour coded in the key. Only interactions between proteins of different subfamilies are depicted. Not all protein combinations have been tested in all species. The absence of an interaction here does not therefore necessarily mean that the proteins do not interact. Publications used to depict interactions among proteins from A. thaliana, P.hybrida and O. sativa are listed in Supplementary Data Table S3.
