Subject: Help FlyBase - wg-GAL4 Hi Alfonso, I am a curating a paper for FlyBase: Glise and Noselli, 1997, Genes Dev. 11(13): 1738 in which they discuss wg-GAL4 provided by you. We do not have this constructs in FlyBase so could you please provide molecular details of the construct (and any references of there are any). I have also queried Stephane for this construct also but I thought there was no harm in asking you too! Thanks for your help, Eleanor Whitfield FlyBase Subject: Re: Help FlyBase - wg-GAL4 The piece that you want to know about is 7.8kb of 5' untranslated control region of wg. This DNA provides all (ALL) functions for the embryonic pattern and contains only a very small and not clear pattern from the adult. Let me know if this is OK Alfonso
