<<Disclaimer: Verify this information before applying it to your situation.>> My name is Joe Murray and for those that dont know me. I am a gastroenterologist at the University of Iowa. I was brought up in the west if Ireland and have been exposed to friends neighbours and more recently patients with celiac disease. We have a dedicated multidisciplinary service for the clinical care of people with celiac disease, which also is involved with clinical research and medical education related to this condition and dermatitis herpetiformis. Our particular interests are in application of serologic tests, atypical presentation and refractory disease. I Look forward to gleening information for my patients from the conference as well as an intellectual interchange of ideas. I will attempt to participate in clinical discussions as my time permits but will not be able address any individual patient questions due to professional and ethical limitations. After that long introduction my question/reply is this: What are the plant toxonomy differences or characteristics that differenciate one grass from another. Do these characteristics always imply a different phylogenetic origin for these plant species. For example buckwheat is not classified as a grass but it sure looks like wheat and tastes like wheat (sort of) and mills like wheat and well you get the idea. Can we depend on the taxonomy as it stands to distinquish the 2 plants as regards the nature of their storage proteins? Joe Murray
