Dear Duncan,

        X-Gluc is routinely used by us plant biologists to localize beta-
glucuronidase (GUS) in plant tissues.  The most common application is promoter
fusions to the GUS gene and then whole plant (for Arabidopsis) or organ (leaf
root, etc for other plants) staining with X-Gluc to give beautiful blue
localizations of gene expression.  See any issue of the Plant Cell for examples
(we propose changing the name of the journal to The Journal of Blue Plants :-))
