Fungi phosphorus compounds

The Porifera Melythoea and the tree Carya sp. are considered accumulator organisms. Yttrium accumulates in bone and teeth, a phenomenon that is explained by its ability to bind to phosphorus-containing compounds, and to polysaccharides. Nucleic acids have high affinities for yttrium, which binds to phosphate at a ratio of 1 3. Yttrium has stimulatory effects on some fungi and other lower organisms. It is believed that yttrium binds to the surface of cells, without penetrating the cell membrane. 

For example, some plants can increase root volume and surface area to optimize uptake potential. Alternatively, plant roots and/or associated fungi can produce chelating compounds that solubilize ferric iron and calcium-bound phosphorus, enzymes and/or acids that solubilize phosphate in the root vicinity. Plants also minimize phosphorus loss by resorbing much of their phosphorus prior to litterfall, and by efficient recycling from fallen litter. In extremely unfertile soils (e.g., in tropical rain forests) phosphorus recycling is so efficient that topsoil contains virtually no phosphorus it is all tied up in biomass.
