The relationships among Mg, growth, chlorophyll synthesis, and cytoplasmic polysome content were studied in Euglena gracilis grown in different levels of the metal. At all levels of magnesium from 20 to 1,600 mumolar, both protein and chlorophyll are formed with exponential kinetics. The apparent rates of synthesis and final yields of both components are greater at higher levels of Mg, but the rate of chlorophyll synthesis always exceeds the rate of protein formation; i.e. the most severely deficient cells contain proportionally more chlorophyll than the sufficient cells. Cytoplasmic polysomes isolated from Mg-deficient Euglena are indistinguishable from those isolated from control cells. We conclude that decreased rates of protein synthesis occur prior to and possibly are causal to decreased rates of chlorophyll synthesis, but that the mechanism of this inhibition remains unclear.
