females were allowed to mate with wild type or mutant males, the females were then dissected and checked for a GFP signal in their reproductive system. 30 minutes after mating, 20% of wild type sperm had accumulated in female storage organs. However, mutant sperm remained in the uterus and failed to be transferred to seminal receptacle and spermathecae, the female sperm storage organs. Ov – ovaries; spt – spermatheca; src – seminal receptacle; ut – uterus; ovd – oviduct.Copyright information:Taken from "Dumpy-30 family members as determinants of male fertility and interaction partners of metal-responsive transcription factor 1 (MTF-1) in "http://www.biomedcentral.com/1471-213X/8/68BMC Developmental Biology 2008;8():68-68.Published online 27 Jun 2008PMCID:PMC2478662.
