Precious Essences: Female Secretions Promote Sperm Storage in Drosophila
Sperm that females receive during mating are stored in special places in the females' reproductive tracts. These storage sites serve to support and retain the sperm, maintaining the sperms' motility and, in mammals, permitting final sperm-maturation. The molecules that attract sperm to these sites and mediate what happens to them there have remained elusive. New research, using elegant genetic ...
متن کاملIn vitro sperm storage with poultry oviductal secretions
In the hen oviduct, tubules have been identified that preserve the sperm, maintaining viability for up to 15 weeks. This study aimed to evaluate the physiological status of rooster sperm when preserved in vitro with uterus vaginal junction secretions (UVJS). Males and females of the Rhode Island breed were used. Sperm aliquots were prepared using Lake extender and Lake extender with UV...
متن کاملDirect visualization of sperm competition and sperm storage in Drosophila
Drosophila females engage in multiple matings [1] [2] [3] [4] even though they can store sperm in specialized organs for most of their life [5]. The existence of sperm competition in Drosophila has been inferred from the proportion of progeny sired by the second male in double-mating experiments [6] [7] [8]. Investigators have used this approach to quantify genetic variation underlying sperm co...
متن کاملFemale genotypes affect sperm displacement in Drosophila.
Differential success of sperm is likely to be an important component of fitness. Extensive variation among male genotypes in competitive success of sperm in multiply mated females has been documented for Drosophila melanogaster. However, virtually all previous studies considered the female to be a passive vessel. Nevertheless, under certain conditions female fitness could be determined by her r...
متن کاملA role for Acp29AB, a predicted seminal fluid lectin, in female sperm storage in Drosophila melanogaster.
Females of many animal species store sperm for taxon-specific periods of time, ranging from a few hours to years. Female sperm storage has important reproductive and evolutionary consequences, yet relatively little is known of its molecular basis. Here, we report the isolation of a loss-of-function mutation of the Drosophila melanogaster Acp29AB gene, which encodes a seminal fluid protein that ...
