His photographic adventure among my potted plants coincided nicely with my recent dilettantish attempts to educate myself about MADS-box genes. These are transcription factors which are paralleled by the homeobox gene products in animals, and are also deeply connected with morphology. Here's a fairly comprehensive site on the subject from the Max-Planck Institute: The MADS-Box Gene Home Page.
