melanogaster sperm sperm storage and competition in females) was first suggested from.
22 Aug The sperm are stored in specialized organs with limited storage capacity, Early studies showed that P2 in D. melanogaster is over increasing as .
Recorded progeny counts should be organized appropriately for easy.
Description:CG, which also encodes a serine-type endopeptidase, is expressed exclusively in the SSC and its transcription is upregulated fold 3—6 h after mating [27]. Intermediate values are usually interpreted as indirect evidence of sperm mixing, which suggests a physiological scenario involving direct sperm competition. New research, using elegant genetic tools in Drosophila, shows that secretory cells associated with a sperm storage organ are important in sperm-supportive functions. Wolfner MF Precious Essences: We also created GAL4-independent reporters by cloning a subfragment of the Send1 or Send2 upstream sequence in front of the coding sequence of a fast-maturing, nuclear-localized, red-fluorescent protein DsRed. A potentially major role of female secretions is in sperm storage.
