Fish egg yolk is largely derived from vitellogenins, which are synthesized in the liver, taken
up from the maternal circulation by growing oocytes via receptor-mediated endocytosis and …

In nonplacental or nontrophotenic vertebrates, early development depends on the maternal
provision of egg yolk, which is mainly derived from large multidomain vitellogenin (Vtg) …

Vitellogenins (Vtgs) are yolk precursor proteins in oviparous species and are cleaved into
three portions–lipovitellin I (LVI), phosvitin (PV), and lipovitellin II (LVII)–in oocytes in …

The spiny ray-finned teleost fishes (Acanthomorpha) are the most successful group of
vertebrates in terms of species diversity. Their meteoric radiation and speciation in the …

The phylogeny of salmonid fishes has been the focus of intensive study for many years, but
some of the most important relationships within this group remain unclear. We used 269 …

Circulatory lipid transport in animals is mediated to a substantial extent by members of the
large lipid transfer (LLT) protein (LLTP) superfamily. These proteins, including …

Embryonic development in nonmammalian vertebrates depends entirely on nutritional
reserves that are predominantly derived from vitellogenin proteins and stored in egg yolk …

The ability of an oocyte to develop into a viable embryo depends on the accumulation of
specific maternal information and molecules. Oocyte growth, particularly in oviparous …

Our understanding of the functions of vitellogenin (Vtg) in reproduction has undergone an
evolutionary transformation over the past decade. Primarily, Vtg was regarded as a female …

The range of the Atlantic salmon spans thousands of kilometres across the North Atlantic.
Throughout the species range, freshwater spawning habitat is highly fragmented such that …
