Host plant metabolism of symbiotically fixed nitrogen in alfalfa (Medicago sativa L.) root nodules



Host plant metabolism of symbiotically fixed nitrogen in alfalfa (Medicago sativa L.) root nodules



Dissertation Abstracts International, B 43(4): 930B



Biochemical comparisons of roots and nodules were made among a symbiotically effective (N2 fixing) type and five types that form symbiotically ineffective nodules. Nodules of ineffective types contained two to tenfold less soluble protein and 10 to 100-fold lower glutamine synthetase (GS), glutamate synthase (GOGAT) and glutamine-dependant asparagine synthetase specific activities than effective nodules.
