FIGURE 1.
Uptake of phosphorus by plants from soil. Two modes of P uptake are present in plants. (A) Direct uptake – between soil and plant root and (B) indirect uptake – through mycorrhizal symbiosis, where AM fungus extra-radical mycelium acquire Pi beyond rhizosphere and Pi transported to intra-radical mycelium as poly-phosphate (Rosewarne et al., 1999).
