Sperm membrane physiology and relevance for fertilization.
This paper aims to overview recent insights in sperm surface remodelling pertinent to fertilization. A basic understanding of this remodelling is required to interpret the high amount of data appearing from high-throughput identification techniques for proteins presently applied in reproductive biology. From the extensive lists of protein candidates identified by proteomics, only a few are reco...

A pot experiment in wire house was conducted to investigate the effect of potassium fertilization on physiology, growth and nutrient uptake of maize. Surface soil s...
متن کاملSperm plasma membrane breakdown during Drosophila fertilization requires sneaky, an acrosomal membrane protein.
Fertilization typically involves membrane fusion between sperm and eggs. In Drosophila, however, sperm enter eggs with membranes intact. Consequently, sperm plasma membrane breakdown (PMBD) and subsequent events of sperm activation occur in the egg cytoplasm. We previously proposed that mutations in the sneaky (snky) gene result in male sterility due to failure in PMBD. Here we support this pro...
متن کاملFertilization and sperm chemotaxis in ascidians.
Prior to fertilization, spermatozoa of many animals and plants show chemotactic behavior toward eggs. Chemotactic behavior was first described in ferns (1), and their attractant was identified as the bimalate ion (2). In animals, sperm chemotaxis to the egg was first observed in the hydrozoan Spirocodon saltatrix (3) and is now widely recognized in all species from cnidarians to human (for revi...
متن کاملDevelopmental sperm contributions: fertilization and beyond.
The objective of this review was to examine the role of the various spermatozoal components suspected of actively participating in early human development. The contributions of the fertilizing spermatozoon to the oocyte include, as a minimum, the delivery of the DNA/chromatin, a putative oocyte-activating factor (OAF), and a centriole. Recent data indicate that spermatozoa may also provide the ...
