A Decaploid Strain of Artemia Salina

A gynandromorph of the brine shrimp, Artemia salina.

S EXUAL mosaics have been reported in three genera of Crustacea. A bilateral mosaic of Carcinus was found to have a testis on one side and a mixed gonad on the other (VEILLET 1945). Gynandromorphs with a testis and ovary have been reported in Homarus (see review by CHACE and MOORE 1959) and in the cladoceran, Simocephalus (BANTA, WOOD, BROWN and INGLE 1939). No intersex or mosaic of Artemia has...

Characterization of the extracellular haemoglobins of Artemia salina.

The following factors were measured for extracellular haemoglobins of Artemia salina: a minimal molecular weight of globin chain per haem group (based on the iron and haem contents), the absorption coefficients, the absorption spectra of various derivatives and the amino acid compositions. These were compared with those of the haemoglobins of other invertebrates. Three Artemia haemoglobins (I, ...

A Single-stranded Nucleic Acid-binding Protein from Artemia salina

A protein that binds tightly to single-stranded but not to double-strained nucleic acids has been purified to homogeneity from a high salt wash of ribosomes from cryptobiotic Artemia salina gastrulae. The protein, designated HD40 to indicate a helix-destabilizing protein with a molecular weight of 40,000, is present in the high-salt ribosomal wash at a level of about 2 molecules per 80 S riboso...

On the metabolism of carotenoids in the crustacean Artemia salina.

Die Zusammensetzung und der Stoffwechsel der Carotinoide in adulten Exemplaren von Artemia salina wurden untersucht. Unabhängig von der Fütterung mit carotinoidfreier Hefe, mit an Oxicarotinoiden reicher Nahrung oder mit Oxocarotinoid-haltigen Algen lassen sich als Hauptpigmente Canthaxanthin (4.4'-Dioxo-/?-carotin) und Echinenon (4-Oxo-/?-carotin) nachweisen. Daneben wur­ den in einer Artemia-...
