The reproductive mode of the female viviparous teleost Poecilia formosa (Poeciliidae) represents the phenomenon known as gynogenesis; that is, parthenogenetic development is initiated by spermatozoa which are needed for physiological activation of the egg and the initiation of gestation, but spermat

Channel catfish, Ictalurus punctatus, leukocyte immune type receptors (LITRs) represent a multigene family that encodes Ig superfamily proteins that mediate activating or inhibitory signaling. In this study, we demonstrate the use of mAb CC41 to monitor viral cytotoxic responses in catfish and deter

Gene sequence similarity due to shared ancestry after a duplication event, that is paralogy, complicates the assessment of genetic variation, as sequences originating from paralogs can be difficult to distinguish. These confounded sequences are often removed prior to further analyses, leaving the un

… Triploid and tetraploid males are very rare among Japanese silver crucian carp due to their gynogenetic reproduction. … These results suggest that gynogenetic development in eggs spawned by tetraploid females should be triggered by tetraploid males' homospecific sperm.四倍体ギンブナ雌雄の自然産卵により得た子孫のDNA 量を調べたところ、全個体が四倍体であった。 …
