Il corso ha come obiettivo lo studio dei meccanismi riproduttivi degli organismi superiori sia animali che vegetali. Riproduzione animale: questa parte del corso sarà focalizzata sullo studio delle principali strategie riproduttive animali e sui meccanismi che regolano la formazione dei gameti e la fecondazione.
The course will be focussed on the male and female reproductive organ development. In particular, the formation of the gametophytes and gametes in Angiosperm will be studied. Furthermore the fertilization process will be studied at cellular and molecular level. The reproductive strategy adapted by Angiosperm to avoid self fertilization will be presented and discussed. Finally alternative reproductive strategies such as apomixes and vegetative reproduction will be discussed Animal reproduction This part of the course will be focous on the principal reproductive strategies and on the mechanisms controlling gamete production and fertilisation. Sexual and asexual reproduction, parthenogenesis Separate sexes and hermaphroditism Invertebrate reproductive dominant strategies and life-cycle adaptation in marine, fresh water and terrestrial habitats Structure and function of gametes. Spermatogenesis and mature sperm cells. Oogenesis and egg structure. Egg components and maternal effect genes. Egg coats: structure and function, molecular components and ZP domain. Fertilisation in Echinoderms, Urochordates, fish and mammals. Zygote formation and activation.
