Phosphorus is an essential nutrient for plants. Green algae usually store excess P as polyphosphate (polyP) in the vacuoles. PolyP, a linear chain of three to hundreds of phosphate residues linked by phosphoanhydride bonds, is important for cell
The vacuole is one of the most conspicuous organelles in plant cells, participating in a series of physiological processes, such as storage of ions and compartmentalization of heavy metals. Isolation of intact vacuoles and elemental analysis
Iron (Fe) is an indispensable micronutrient for plant growth and development. Since both deficiency, as well as a surplus of Fe, can be detrimental to plant health, plants need to constantly tune uptake rates to maintain an optimum level of Fe.
