Based on electron microscopic studies and visualization of calcium with the Ca indicator pyroantimonate, it was established that a prolonged incubation of the bean (Vicia faba L.) root nodules and isolated symbiosomes in EGTA-containing buffer depletes calcium in these nitrogen-fixing units. Other experiments demonstrated that the induction of calcium(More)
The capacity of symbiosomes from yellow lupin root nodules for active Ca2+uptake and the sensitivity of their nitrogenase activity to a disturbance of the symbiotic Ca partition were investigated. The experiments carried out on the isolated symbiosomes and the peribacteroid membrane (PBM) vesicles, using Ca2+indicators arsenazo III and chlorotetracycline,(More)
