Journal ArticleDOI
Facilitated oxygen diffusion. The role of leghemoglobin in nitrogen fixation by bacteroids isolated from soybean root nodules.
TL;DR: It is deduced that oxyleghemoglobin and other oxygenbinding proteins exert their effects by facilitating the diffusion of oxygen through a thin layer of solution, the "unstirred layer," surrounding the bacteroids, which results in the "effective" oxygen uptake which supports nitrogenase activity.
Journal ArticleDOI
The Kinetics of the Reactions of Leghemoglobin with Oxygen and Carbon Monoxide
TL;DR: It is suggested that leghemoglobin-facilitated oxygen diffusion serves not only to augment the influx of oxygen, but serves as well to make the oxygen pressure within the nodule or cell everywhere nearly the same.
Journal ArticleDOI
Direct detection of radicals in intact soybean nodules : presence of nitric oxide-leghemoglobin complexes
TL;DR: Results suggest that there are characteristic changes in both the metal ion complexes and radicals present in intactRoot nodules of different ages, and support the theory that nitric oxide and other radicals play a significant role in determining the nitrogen fixing activity of root nodules.

Determination of leghemoglobin in legume nodules
D.O. Wilson,H.M. Reisenauer +1 more
TL;DR: A method is described for the determination of LHb in legume root nodule tissue and it is shown that the procedure requires a minimum of specialized equipment and reagents, and is rapid and reproducible.
Journal ArticleDOI
The effect of ammonium nitrate on the synthesis of nitrogenase and the concentration of leghemoglobin in pea root nodules induced by Rhizobium leguminosarum.
TL;DR: In this paper, the effects of NH4NO3 on the development of root nodules of Pisum sativum after infection with Rhizobium leguminosarum (strain PRE) and on the nitrogenase activity of the bacteroids in the nodule tissue were studied.
