Retroposons of salmonoid fishes (Actinopterygii: Salmonoidei) and their evolution
Gene, 2009Short and long retroposons, or non-LTR retrotransposons (SINEs and LINEs, respectively) are two groups of interspersed repetitive elements amplifying in the genome via RNA and cDNA-mediated reverse transcription. In this process, SINEs entirely depend on the enzymatic machinery of autonomous LINEs.

Polypteridae (Actinopterygii: Cladistia) and DANA-SINEs insertions
Marine Genomics, 2010SINE sequences are interspersed throughout virtually all eukaryotic genomes and greatly outnumber the other repetitive elements. These sequences are of increasing interest for phylogenetic studies because of their diagnostic power for establishing common ancestry among taxa, once properly characterized. We identified and characterized a peculiar family

Denticles in fossil Actinopterygii.
Journal of Cell Science, 1942ABSTRACT It has long been known that true denticles, as opposed to mere ridges, tubercles, or spines of the outer ganoine layer may occur on the exposed surface of the scales and dermal bones of living Actinopterygii such as Poly pt er us orLepidosteus.

Ray-finned fishes (Actinopterygii)
2009Abstract Actinopterygii, or ray-Anned Ashes, are one of the two major lineages of osteichthyan vertebrates, the other being Sarcopterygii (1). 7ere are more than 26,890 species of actinopterygian Ashes and the group has diversiAed into a wide range of marine and freshwater habitats (2).

Osteichthyes: Immune Systems of Teleosts (Actinopterygii)
2018Teleosts and elasmobranchs are the lowest vertebrates that possess adaptive immunity akin to mammalian ones. However, the fish immune system is different from that of mammals, that is, a lack of bone marrow, lymph nodes and germinal center. Their immune system is also characterized by the fact that their surface is covered by live cells with mucus in ...

ACTINOPTERYGII, Strahl(en) flosser
2010Die Actinopterygii bilden den uberwiegenden Teil der rezenten Fischfauna, wah rend die Fischformen der Sarcopterygii (S. 307) heute nur noch mit wenigen Arten der Dipnoi (Lungenfische) (S. 309) und Actinistia (Hohlstachler) (S. 315) vertreten sind. Der Name „Strahlflosser“ bezieht sich auf die strahlenformig angeordneten Lepidotrichia, die die Flossen ...
