Ultrastruktura, energie a kompetice spermií: Komparativní studie s využitím dvou modelových druhů chrupavčitých a kostnatých ryb
Annotation in Czech
The proposed project will deal with spermatozoa ultrastructure, energetic and competition in two groups of model species of chondrostean (Chondrostei) and teleostean (Teleostei) fish. Study on the spermatozoa ultramorphology and ultrastructure in fish, specially focused on structure of axoneme and midpiece, to better understand the roles of mitochondria and basal body structures. This also involves studies of micromechanics and micro hydrodynamics of integrated machinery of axoneme with its associated membrane. Factors reviving motility and fertilizability in "exhausted" spermatozoa of intact and demembranated spermatozoa of fish species. We anticipate the determination of activation/inhibition factors in both fish groups and firstly demonstrate that spermatozoa are able or unable fertilize the eggs with assessment of acrosome integrity. Energy requirement of machinery during spermatozoa motility for understanding why duration of motility is so short with evaluation of ATP level. Investigate the
