Research Description: Segregation Distorter (SD) is a meiotic drive gene complex found in natural populations of Drosophila melanogaster. It causes heterozygous SD+/SD males to produce almost exclusively SD sperm. SD was first discovered in Madison about 50 years ago, and much has been learned about its genetic mechanism and molecular basis. The Sd mutant encodes a truncated version of the nuclear transport protein RanGap. I have been studying a dominant suppressor of SD, one that restores the Mendelian ratio, as an entree to defining other steps in the sperm transmission pathway and to further understand the population dynamics of the SD system. Currently, I am conducting a screen for gamma-ray induced revertants of Su(SD) in order to cytologically pinpoint the physical location of the mutation.
