Mitochondrial Biogenesis during Differentiation of Artemia Salina Cysts

Mitochondria isolated from cysts of Artemia salina (brine shrimp) were found to be devoid of cristae and to possess a low respiratory capability. Hydration of the cysts induces marked biochemical and morphological changes in the mitochondria. Their biogenesis proceeds in two stages. The first stage is completed within 1 h and is characterized by a rapid increase in the respiratory capability of...

Short Communication Long-term Anoxia in Artemia Cysts

Among the many adaptations associated with the rigorous life history of the brine shrimp, Artemia, is the striking resistance of the encysted embryo (cyst) to oxygen lack (anoxia). Dutrieu and Chrestia-Blanchine (1966) reported that these cysts could be incubated in sea water under anoxic conditions for over 5 months without a decrease in viability. Subsequent work showed that anoxic cysts did ...

Effect of Initial Ozonation on the Hatching Rate of Artemia Cysts

In an experiment to investigate the bio-excitatory effect of ozone gas on the hatching of artemia cysts, it was found that limited blown ozone gas has an effect on significant increasing of the hatching time of artemia cysts, though artemia cycsts are very resistant to ozone. The cysts hatching were done intitialy using 50, 35, 15, 10 and 5 mg of ozone blowing into one-liter containers that las...

Regulation of trehalase expression inhibits apoptosis in diapause cysts of Artemia.

Trehalase, which specifically hydrolyses trehalose into glucose, plays an important role in the metabolism of trehalose. Large amounts of trehalose are stored in the diapause encysted embryos (cysts) of Artemia, which are not only vital to their extraordinary stress resistance, but also provide a source of energy for development after diapause is terminated. In the present study, a mechanism fo...

Involvement of Cyclin K Posttranscriptional Regulation in the Formation of Artemia Diapause Cysts

BACKGROUND Artemia eggs tend to develop ovoviviparously to yield nauplius larvae in good rearing conditions; while under adverse situations, they tend to develop oviparously and encysted diapause embryos are formed instead. However, the intrinsic mechanisms regulating this process are not well understood. PRINCIPAL FINDING This study has characterized the function of cyclin K, a regulatory su...
