Nucleotide metabolism during brine shrimp embryogenesis.
Changes in the amounts of acid-soluble nucleotides during embryonic development of the encysted egg of the brine shrimp, Artemia salina, have been determined. Significant quantities of diguanosine tetraphosphate, the most abundant compound in the nucleotide pool, are apparently not utilized until hatching, at which time the amount falls precipitously. Diguanosine triphosphate, a homologue of th...
متن کاملMolecular phylogenetics and asexuality in the brine shrimp Artemia.
Explaining cases of long-term persistence of parthenogenesis has proven an arduous task for evolutionary biologists. Interpreting sexual-asexual interactions though has recently advanced owing to methodological design, increased taxon sampling and choice of model organisms. We inferred the phylogeny of Artemia, a halophilic branchiopod genus of sexual and parthenogenetic forms with cosmopolitan...
متن کاملPurification and characterization of phenoloxidase from brine shrimp Artemia sinica.
Phenoloxidase from Artemia sinica (AsPO) was purified by Superdex 200 gel-filtration and Q Sepharose fast flow ion-exchange chromatography, and its properties were characterized biochemically and enzymatically by using L-dihydroxyphenylalanine (L-DOPA) as the specific substrate. Results showed that AsPO was isolated as a monomeric protein of 125.5 kDa in molecular mass. The optimal pH value and...
متن کاملThe Brine Shrimp Artemia: Adapted to Critical Life Conditions
The brine shrimp Artemia is a micro-crustacean, well adapted to the harsh conditions that severely hypersaline environments impose on survival and reproduction. Adaptation to these conditions has taken place at different functional levels or domains, from the individual (molecular-cellular-physiological) to the population level. Such conditions are experienced by very few equivalent macro-plank...
متن کاملBrine shrimp lethality bioassay of selected Indian medicinal plants.
Ethanolic extracts of six Indian medicinal plants, piperine, guggulsterone E and guggulsterone Z were tested for cytotoxicity using brine shrimp lethality test. Piper longum showed most potent cytotoxic activity. Piperine, guggulsterone E and guggulsterone Z showed potent activity with LC(50) 2.4, 8.9 and 4.9, respectively.
