Sperm production and male fertility in Drosophila melanogaster depend on transcripts generated from the AAGAG(n) repeated satellite DNA within primary spermatocytes.
A whole-genome genetic screen links new aspects of oocyte maturation to proteostasis renewal in the immortal Caenorhabditis elegans germ-cell lineage and reveals similarities to somatic cell maintenance during aging.
Gamete release in the jellyfish Clytia is mediated by an opsin photopigment expressed in neurosecretory cells of the gonad ectoderm, which release an oocyte maturation hormone in response to light.
Cyclic estrogen signaling in oviduct epithelial cells suppresses oviduct luminal protease activity to allow survival and development of preimplantation embryos
The slope of the chemoattractant concentration gradient is a driving force for sperm chemotaxis, by coordinating the entrainment of information flow between sensing, signaling and motility.
