Legume nodules from nutrient-poor soils exhibit high plasticity of cellular phosphorus recycling and conservation during variable phosphorus supply

Vardien, Waafeka; Steenkamp, Emma Theodora; Valentine, Alex J. (Elsevier, 2016-02)

Nitrogen fixing legumes rely on phosphorus for nodule formation, nodule function and the energy costs of fixation. Phosphorus is however very limited in soils, especially in ancient sandstone-derived soils such as those ...
Nodules from fynbos legume Virgilia divaricata have high functional plasticity under variable P supply levels

Vardien, Waafeka; Mesjasz-Przybylowicz, Jolanta; Przybylowicz, Wojciech J.; Wang, Yaodong; Steenkamp, Emma Theodora; Valentine, Alex J. (Elsevier, 2014-11)

Legumes have the unique ability to fix atmospheric nitrogen (N2) via symbiotic bacteria in their nodules but depend heavily on phosphorus (P), which affects nodulation, and the carbon costs and energy costs of N2 fixation. ...
