Phloemeomics (flō-mē-ō-mics): the science of understanding phloem structure and function by cataloguing and characterizing all genes expressed in the phloem.  Below is an Adobe PDF file of a poster describing some of our work using phylogenetic footprinting to understand phloem gene expression.  (The poster is compressed to fit on letter size paper.  To facilitate reading, print or magnify to >200%.)
