The following information accompanied stocks donated to the Bloomington Drosophila Stock Center by Parsa Kazemi-Esfarjani, University of California at San Diego. A number of insertions recovered as suppressors or enhancers in a screen for modifiers of eye phenotypes caused by polyglutamine expression have been mapped. See Kazemi-Esfarjani and Benzer, 2000 (Genetic suppression of polyglutamine toxicity in Drosophila, Science, 287:1837 ) (FBrf0126796) for more details on the screen. A. Insertions recovered as suppressors in the screen. P{EP}EU119EU119 is a viable insertion on the third chromosome at sequence coordinate 3L:639710 (Release 5; plus strand). P{EP}DdrEU173 is a viable insertion on the second chromosome at sequence coordinate 2L:6256701 (Release 5; plus strand). P{EP}EU820EU820 is a viable insertion on the third chromosome at sequence coordinate 3L:639690 (Release 5; plus strand). P{EP}CamEU1250 is an insertion on the second chromosome at sequence coordinate 2R:8149182 (Release 5; minus strand). P{EP}scatEU2290 is a viable and fertile insertion on the second chromosome at sequence coordinate 2L:9431052 (Release 5; plus strand). P{EP}wechEU2335 is a viable insertion on the second chromosome at sequence coordinate 2R:3377350 (Release 5; minus strand). P{EP}CG6115EU4801 is a viable insertion on the second chromosome at sequence coordinate 2L:16887971 (Release 5; minus strand). B. Insertions recovered as enhancers in the screen. P{EP}esgEU143 is a viable and fertile insertion on the second chromosome at sequence coordinate 2L:15333734 (Release 5; plus strand).
