Check any number of papers written by Richard A. Jefferson who first used GUS
as a reporter gene in plants.  There also is a book called GUS protocols which
may be of help.

GUS Protocols: Using the GUS gene as a Reporter of Gene Expression
Editited by Sean R. Gallagher
Academic Press 1992   ISBN 0-12-274010-6

Hope this helps
