Phosphate (Pi) Uptake

  • Gyanendra Nath Mitra


It is estimated that globally there is more than 30 % yield loss of crops due to P deficiency. Under conditions of P deficiency, plants adapt themselves suitably through modification of their roots and shoots so as to acquire more Pi from soil and use them frugally to support plant growth. Phosphate deficiency results in coordinated induction of hundreds of genes encoding enzymes, which maximise capacity of plants to acquire phosphate more efficiently from external sources and reprioritise internal use of phosphorus.

Phosphate (Pi) use efficiency (PUE) of crops is generally low (<15–20 %) due to various soil- and plant-related factors. Different approaches made to improve PUE including transgenic technologies have been discussed.
