Summary

The ribosomes of the naked flagellateDunaliella spec. which belongs to theVolvocales were isolated and characterized at different Mg2+-concentrations by isokinetic density sedimentation. 80 s ribosomes from the cytosol as well as 70 s ribosomes from the chloroplast are very sensitive against Mg2+-deprivation. The biological meaning of this strong Mg2+-dependence ofDunaliella ribosomes is discussed.
