Étude de la structure ovarienne de Barbus holotaenia, Boulenger, 1904 (Pisces, Cyprinidae) du bassin de la Luki (Zaïre)

Knowledge and Management of Aquatic Ecosystems, 1996
L'examen histologique et cytologique des ovaires de Barbus holotaénia a permis de distinguer différents stades de développement.(stades 0 à VI). Le stade 0 correspond à la transformation des cellules primordiales en ovocytes.

In vitro assessment of Na+, Mg2+, Ca2+, and K+ on vitellogenesis and expression of genes related to ovarian development in female Chinese mitten crab, Eriocheir sinensis

Aquaculture Reports
Seawater contains a variety of mineral ions, such as Na+, Mg2+, Ca2+, and K+. Although previous studies have shown that brackish water can promote ovarian development of the Chinese mitten crab (Eriocheir sinensis), it remains unclear whether these ions ...

Nutritional Effects on Vitellogenesis in Species of Drosophila

Journal of Entomological Science, 2000
A comparative study of vitellogenesis in response to feeding was made in females of three species of the genus Drosophila, belonging to different species groups. The process of vitellogenesis, although conservative, shows significant differences in species phylogenetically distant to D. melanogaster (Meigen). Females of D.

Transduction of the vitellogenic signal of juvenile hormone by Methoprene-tolerant in the cockroach Blattella germanica (L.) (Dictyoptera, Blattellidae) [PDF]

Arthropods, 2016
In adult females of the cockroach Blattella germanica, juvenile hormone (JH) promotes vitellogenin production. Depletion of Methoprene-tolerant (Met) mRNA levels with RNAi resulted in a clear reduction of vitellogenin expression in the fat body while ...
