(Chondrostei, Acipenseriformes)

, 2018
Spermatogenesis was investigated in the Adriatic sturgeon, Acipenser naccarii, by light and electron microscopy. The testis of the unrestricted type had a germinal compartment composed of lobules containing germ cells and Sertoli cells, and separated by ...

The fate of the duplicated androgen receptor in fishes: a late neofunctionalization event?

BMC Evolutionary Biology, 2008
Background Based on the observation of an increased number of paralogous genes in teleost fishes compared with other vertebrates and on the conserved synteny between duplicated copies, it has been shown that a whole genome duplication (WGD) occurred ...

Multiple source genes of HAmo SINE actively expanded and ongoing retroposition in cyprinid genomes relying on its partner LINE

BMC Evolutionary Biology, 2010
Background We recently characterized HAmo SINE and its partner LINE in silver carp and bighead carp based on hybridization capture of repetitive elements from digested genomic DNA in solution using a bead-probe 1.

A review of the lower actinopterygian phylogeny

, 2005
A review of lower actinopterygian phylogeny has led us to the conclusion that the Cladistia are the sister group of Recent actinopterygians (Actinopteri) and that the extinct Palaeonisciformes are a paraphyletic group, comprising stem-group ...

Mitochondrial Genomes of Distant Fish Hybrids Reveal Maternal Inheritance Patterns and Phylogenetic Relationships

Diversity
As distant hybridization has profound implications for evolutionary biology, aquaculture, and biodiversity conservation, this study aims to elucidate patterns of maternal inheritance, genetic divergence, and phylogenetic relationships by synthesizing ...

On the sources of development of the fish skeleton muscles

, 1968
An investigation of the sources of development of skeleton muscles of Acipense-riformes, Selachii and Teleostei showed that in Teleostei the dermatome takes part in the formation of muscle fibres of the myotome and a body wall.
