Hi Netters

	In response to a previous request for information on measuring GUS
activity in tomato;

	Most plants studied (42 out of 49) show endogenous GUS activity!

Beware, those of you trying to use GUS as a transgenic reporter.  Tomato, of
course, would have to be one of the ones showing such endogenous GUS activity.
Tobacco and Arabidopsis are both safe though.  :-)
	For complete details, see:

Intrinsic GUS-like activities in seed plants.
C. Y. Hu, P.P. Chee, R.H. Chesney, J.H. Zhou, P.D. Miller, and W.T. Obrien,
Plant Cell Reports, 9, 1-5 (1990).

	Hope this helps a few folks strugling with spurious GUShings of blue.
