Title
First observation of diffusion‐limited plant root phosphorus uptake from nutrient solution
JAKOB SANTNER; ERIK SMOLDERS; WALTER W. WENZEL; et al. Plant Cell & Environment 2012. doi:10.1111/j.1365-3040.2012.02509.x
Other claims from this paper (9)
- Intervention effect Passive diffusion-based sampler uptake increased up to 40-fold.
- Observation The study found experimental evidence of diffusion-limited P uptake by plant roots from solution.
- Observation The Michaelis constant was 10.4 µmol L(-1) in unbuffered solutions.
- Observation The Michaelis constant was approximately 0.5 µmol L(-1) in the buffered system.
- Mechanism The authors infer that constants measured in unbuffered solutions do not represent transporter affinity.
- Mechanism Increasing carrier affinity is unlikely to improve plant P uptake efficiency.
- Mechanism Increasing root surface area is more likely to enhance P uptake.
- Mechanism Exudation of P-solubilizing compounds is more likely to enhance P uptake.
- Mechanism Natural nanoparticles may have an important role in plant P nutrition.
