... in the autumn, encysted embryos of the brine shrimp, Artemia franciscana , can encounter prolonged bouts of anoxia when buried in anoxic sediments, algal mats and windrows of other embryos along the shore ( Clegg,1974 ). Not surprisingly, these embryos possess a profound mechanism of ensuring long-term...

... in animal mitochondrial gene expression. We have used embryos of the brine shrimp Artemia franciscana to test hypotheses regarding message stability and polyadenylation under conditions simulating anoxia-induced quiescence. In response to anoxia, these embryos undergo a profound and acute metabolic...

...Brian D. Eads; Steven C. Hand SUMMARY In response to anoxia, embryos of the brine shrimp Artemia franciscana are able coordinately to downregulate metabolism to levels low enough to permit survival for several years at room temperature. In addition to dramatic decreases in free ATP levels and heat...

...Frank Van Breukelen; Ryan Maier; Steven C. Hand ABSTRACT Transcriptional activity, as assessed by nuclear run-on assays, was constant during 10 h of normoxic development for embryos of the brine shrimp Artemia franciscana . Exposure of embryos to only 4 h of anoxia resulted in a 79.3±1 % decrease...

...J. I. Spicer; M. M. El-Gamal ABSTRACT The ability to regulate O 2 uptake during exposure to acutely declining O 2 tensions developed early (stage 6) in the brine shrimp Artemia franciscana and co-occurred with the appearance of a functional heart and gills. Culture under chronic hypoxia resulted...

...A. H. Warner; S. A. Jackson; J. S. Clegg ABSTRACT Hydrated encysted embryos of the brine shrimp Artemia franciscana have the ability to withstand years in anaerobic sea water using metabolic strategies that enable them to inactivate all cell metabolic activities and then to resume development when...
