Data are presented for relationships between concentrations of free, dissolved O 2 ([O 2 ]) and respiration and between respiration and nitrogen fixation by soybean bacteroids during microaerobic steady states in flow chamber reactions. In these, O 2

Respiration and nitrogen fixation in legume root nodules is considered to be limited by the rate at which O2 from the atmosphere can enter nodules. A thin diffusion barrier in the inner cortex, restricts access to the central tissue where there is a

The infected cells of soybean (Glycine max) root nodules require ATP production for ammonia assimilation and purine synthesis under microaerobic conditions. It is likely that the bulk of this demand is supplied through mitochondrial oxidative phospho

In Australia, lucerne responds to inoculation with Rhizobium meliloti . There are consequent benefits to N 2 fixation during and immediately after establishment but little is known about lucerne's capacity to fix N 2 in mature stands. Root nodules ar

Azoarcus sp. strain BH72 is an aerobic diazotrophic bacterium that was originally found as an endophyte in Kallar grass. Anticipating that these bacteria are exposed to dissolved O2 concentrations (DOCs) in the nanomolar range during their life cycle

A liquid reaction medium containing dissolved air, oxyleghaemoglobin and low concentrations (0-2 mM) of glucose, succinate, malate or ethanol, was supplied to bacteroids prepared from soybean root nodules and confined in a stirred reaction chamber. M

There are conflicting reports in the literature of the possible role of the ureides, allantoin and allantoic acid, in the nitrogen economy of Arachis species. Therefore, xylem sap composition in food peanut (Arachis hypogaea L.), and two forage peanu

The concentrations of poly-$\beta $-hydroxybutyrate (PHB) and of total $\beta $-hydroxybutyrate (total HB = PHB + non-polymeric forms) were determined in bacteroids prepared from root nodules of field- and glasshouse-grown soybeans. Results showed th

Suspensions of bacteroids prepared from root nodules of glasshouse-grown soybeans were studied in a stirred chamber supplied with variable flows of solutions containing dissolved air, oxyleghaemoglobin and various energy sources. In experiments of up

A liquid reaction medium containing dissolved air and oxyleghaemoglobin, but no energy-yielding substrate, was supplied to bacteroids confined in a stirred flow reaction chamber. The relative oxygenation of the leghaemoglobin in the chamber was deter
