The Drosophila melanogaster X-linked mfs(1)6E locus is required for production of normal seminal fluid by the male accessory glands.
The Drosophila male accessory glands (paragonias) are two male-specific organs that produce seminal fluid, a secretion involved in sperm storage and subsequent sperm utilization by the female. This paper reports the first X-linked locus, male-female-sterile in region 6E [mfs(1)6E], required for the production of normal seminal fluid. Mutant males produce motile spermatozoa, which are transferred to females during mating, but which are not stored. Sterility of these males is mainly due to severe affected transfer of seminal fluid to females during mating. In addition, the mutant seminal fluid seems defective in triggering the behavioral (reduced receptivity to further mating) and physiological (increased egg-laying) changes normally observed in mated females. Mutant male accessory glands show notable abnormalities, connected with glandular secretion as well as qualitative and quantitative differences in their protein content.
