Thiol-based redox signaling in the nitrogen-fixing symbiosis
In nitrogen poor soils legumes establish a symbiotic interaction with rhizobia that results in the formation of root nodules. These are unique plant organs where bacteria differentiate into bacteroids, which express the nitrogenase enzyme complex that reduces atmospheric N 2 to ammonia. Nodule metabolism requires a tight control of the concentrations of reactive oxygen and nitrogen species (RON...
متن کاملNitrogen yield and nitrogen use of chickpea compared to pea, barley and oat in Central Europe
European agriculture suffers from a substantial deficit of protein sources forlivestock and the projected changes in agro-climatic conditions in Central Europeinclude a higher risk of drought. To address these challenges, the drought resistantlegume crop chickpea was compared with pea, barley and oat regarding its nitrogen(N) yield, protein yield and N use and utilization efficiency under Centr...
متن کاملNitrogen Fixing
Blue Green Algae (BGA) have the capacity to self generate photosynthates from CO and 2 water. It is gratifying to note that Aulosira is the most important alga of the rice fields of India. Algalization has been found to benefit all the growth parameters. The propagation of BGA enriches the N status of soil and also provides organic matter and biological quotient 2 substances for plant growth. T...
متن کاملNitrogen metabolism in the isolated perfused rat liver. Nitrogen balance, redox state and rates of proteolysis.
Nitrogen balances were measured in isolated perfused rat livers in the presence and absence of nitrogen donors. In all instances the balance apparently was incomplete. The expression [alanine][alpha-oxoglutarate]/[pyruvate][glutamate] remained fairly constant under the metabolic conditions studied, indicating that it may be at near-equilibrium. The source of the extra nitrogen seems to be deriv...
متن کاملFerredoxins from Nitrogen-Fixing Bacteria
Two ferredoxins have been purified from N2-fixing Mycobacterium flavum. Ferredoxin I had a minimum molecular weight (by amino acid analysis) of 11 230 and contained 7.4 mol Fe and 7.0 mol S2per mol. The ratio of the absorbance at 400 nm to that at 275 nm was 0.7. Ferredoxin I1 had a minimum molecular weight of 13478 and contained 3.4 mol Fe and 3.2 mol S2per mol. The ratio of the absorbance at ...
