“…Nevertheless, the effect of seedlings on plant growth was weaker than on nodule formation and development, suggesting thus that P had a direct and positive stimulation of nodulation in legumes ( Jakobsen 1985, Israel 1987, 1993, Sanginga et al 1989, Hellsten and Huss-Danell 2001. However, an elevated P level appeared to increase nodule development, which is in agreement with our previous reports (Miao et al 2007) and other reports on soybean (Singleton et al 1985, Drevon andHartwig 1997).…”

“…It is known that P regulation of photosynthesis and carbohydrate metabolism in leaves was one of the major factors limiting the plant growth (Marschner 1986). Moreover, P has stimulating effects on nodule growth and nitrogenase activity in nodules of legumes (Jakobsen 1985, Israel 1987, Hart 1989, Tang et al 2001); on the contrary its deficiency decreased nodule mass (Singleton et al 1985, Israel 1987, Ribet and Drevon 1995, Drevon and Hartwig 1997, nodule number ( Jakobsen 1985, Tang et al 2001) and nitrogenase activity (Sa and Israel 1991).…”

The effect of three seedling treatments: T 0 , normal germination; T 1 , cotyledons removed; T 2 , cotyledons removed 5 days earlier than in T 1 ; and two phosphorus levels (P 0 and P 30 ) on nodulation and nodule function in soybean [Glycine max (L.) Merr.] were investigated in nutrient solution culture. The number of nodules formed at P 0 was in the order T 2 > T 0 > T 1 , but it was T 0 > T 2 > T 1 at P 30 . Nodule dry weight per plant had the same tendency as the nodule number. Nodule size (dry weight per nodule) in seedlings ranged from 0.601 to 1.089 mg in the order T 0 > T 1 > T 2 , regardless of P level. For example, nodule size in T 0 was larger by 86% and 52% than T 2 at P 0 and P 30 , respectively. Furthermore, regardless of P level, a specific acetylene reduction activity (ARA, µM C 2 H 4 /h/g nodule) increased with P content in seedlings, but no significant difference was found (P < 0.05). Leghemoglobin (Lb) content was not significantly affected by P level; however, seedlings (T 0 and T 1 ) significantly affected the Lb content per unit plant biomass (P < 0.05). All these results suggest that seedling P content plays a key role in nodulation and nodule function of soybean.

“…N 2 -fixing legumes are autonomous at acquiring N, but depend profoundly on and require more P than legumes growing on mineral N (Drevon and Hartwig 1997). Phosphorus not only affects the energy costs of N 2 fixation (Schulze et al 1999, Valentine et al 2010, it is also important for nodule formation and function (Israel 1987).…”

Legumes have the unique ability to fix atmospheric nitrogen (N 2 ) via symbiotic bacteria in their nodules but depend heavily on phosphorus (P), which affects nodulation, and the carbon costs and energy costs of N 2 fixation. Consequently, legumes growing in nutrient-poor ecosystems (e.g. sandstone derived soils) have to enhance P recycling and/ or acquisition in order to maintain N 2 fixation. In this study, we investigated the flexibility of P recycling and distribution within the nodules and their effect on N nutrition in Virgilia divaricata Adamson, Fabaceae, an indigenous legume in the Cape Floristic Region of South Africa. Specifically, we assessed tissue elemental localization using micro-particle induced x-ray emission 1 (PIXE), measured N fixation using nutrient concentrations derived from inductively coupled mass spectrometry (ICP-MS), calculated nutrient costs, and determined P recycling from enzyme activity assays. Morphological and physiological features characteristic of adaptation to P-deprivation were observed for V. divaricata. Decreased plant growth and nodule production with parallel increased root: shoot ratios are some of the plastic features exhibited in response to P deficiency. Plants resupplied with P resembled those supplied with optimal P levels in terms of growth and nutrient acquisition. Under low P conditions, plants maintained an increase in N 2 -fixing efficiency despite lower levels of orthophosphate (Pi) in the nodules.This can be attributed to two factors: i) an increase in Fe concentration under low P, and ii) greater APase activity in both the roots and nodules under low P. These findings suggest that V. divaricata is well-adapted to acquire N under P deficiency, owing to the plasticity of its nodule physiology.

“…The hydroaeroponic culture used in this work induced a numerous nodulation. Subsequently, the ratio total biomass/nodule biomass was lower than in conditions where legumes were grown with a solid substrate, as shown for the same biological material in Drevon and Hartwig [5] compared to Ribet and Drevon [16]. Therefore, each individual nodule may function at a much lower steady-state rate within hydroaeroponic culture than within solid support.…”

-Nodule conductance to O 2 diffusion in Phaseolus vulgaris was calculated from the in situ measurement of the response of nodulated-root O 2 uptake to variations of rhizospheric partial pressure of O 2 at the flowering stage for nodulated-plants grown hydroaeroponically in a glasshouse. Comparing common bean lines BAT477, CocoT, DOR364, Flamingo and NAG310, the nodule O 2 uptake at ambient pO 2 was the highest (372 µmol O 2 ⋅h -1 ⋅pl -1 ) for BAT477 in symbiosis with the reference strain Rhizobium tropici CIAT899. The maximal value (2800 µmol O 2 ⋅h -1 ⋅pl -1 ) was observed at 50 kPa O 2 . This was associated with the lowest nodule conductance (4.5 µm⋅s -1 ), though the latter was higher with the native strain Sinorhizobium fredii 1a6. The highest nodule conductance (7.5 µm⋅s -1 ) was observed for the less efficient symbiosis CocoT-CIAT899. It is argued that nodule conductance is an adaptation mechanism to respond to plant N demand in compensation for low nodulation or the high respiratory cost for nitrogen fixation in some symbioses. nodule conductance / oxygen diffusion / Phaseolus vulgaris / Rhizobiaceae / symbiosis Résumé -Variabilité génotypique de la conductance nodulaire à la diffusion de l'oxygène chez le haricot (Phaseolus vulgaris). La conductance nodulaire à la diffusion d'oxygène chez Phaseolus vulgaris a été calculée par la mesure in situ à la floraison de la réponse de la consommation d'O 2 à des variations de pO 2 rhizosphérique sur des racines nodulées de plantes en culture hydroaéro-ponique sous serre vitrée. Comparant les lignées de haricot BAT477, CocoT, DOR364, Flamingo et NAG310, la consommation nodulaire d'O 2 a été la plus élevée à la pO 2 ambiante (372 µmol O 2 ⋅h -1 ⋅pl -1 ) pour la symbiose de BAT477 avec la souche de référence Rhizobium tropici CIAT899. Elle a atteint la valeur maximale de 2800 µmol O 2 ⋅h -1 ⋅pl -1 à 50 kPa O 2 . Elle est associée à la plus faible conductance nodulaire (4.5 µm O 2 ⋅s -1 ) alors que cette dernière est plus élevée avec la souche native Sinorhizobium fredii 1a6. La conductance la plus élevée (7.5 µm O 2 ⋅s -1 ) est observée chez la symbiose CocoT-CIAT899. Il est suggéré que l'augmentation de conductance nodulaire observée chez certaines symbioses est un mécanisme d'adaptation pour répondre à la demande en azote de la plante en compensation d'une faible masse nodulaire ou d'un fort coût respiratoire lié à l'activité nitrogénase.
