Theses and Dissertations
Barley plants grown in Mg, Mn, Zn and Cu deficient media were analyzed for specific activity, total activity and amount of RuDPCase present. Percent dry weight, as well as chlorophyll and soluble protein content were determined. All deficiencies caused lower chlorophyll and RuDPCase concentrations than occurred in the control. Soluble protein content, however, was higher in all deficient plants than in the control, either on a dry or a fresh weight basis. The addition of 18 μM Mn^2+ increased the activity of Mg^2+ containing RuDPCase preparations as much as 133% above normal. The specific activity of RuDPCase from Mg, Mn, …
