Abstract
The availability of phosphorus, an essential macronutrient for plant growth, is often limiting, even in soils with a high P content. To overcome limitations in P supply plants have evolved a variety of highly specialized physiological, biochemical and molecular response mechanisms to acquire inorganic phosphate ions (Pi) from the soil (see Raghothama, 1999). These mechanisms include; changes in plant morphology, the secretion of protons, organic acids, RNases and acid phosphatases, from roots to solubilize P-containing compounds in the soil, and enhanced Pi uptake through the activation of Pi transporters.
