Molecular responses of plant to phosphate starvation


, : Molecular responses of plant to phosphate starvation. Postepy Biologii Komorki 30(4): 647-665

The deficiency of available for plants inorganic phosphate (Pi) in the environment is a common phenomenon. Plants adapt to such stress conditions by developing a number of mechanisms, e.g. increasing Pi uptake from soil and/or Pi mobilization from intercellular pools. Plant roots can secrete organic acids, acid phosphatase and, if necessary, also ribonucleases to the ground with simultaneous induction of Pi transporters and numerous phosphatases in cells. These changes are usually preceded or accompanied by activation or repression of specific genes. Under phosphate starvation conditions the induction of genes encoding Pi transporters, acid phosphatases, ribonucleases, beta-glucosidase and others was observed in roots. To react fast and adequately to the variety of environmental changes plants require efficient signal perception and transduction systems. Little is known about mechanisms of Pi signaling, however this problem is recently under extensive study. Studies on the function of hormones, phosphonate, Pi transporters and other factors in signal transduction are currently underway. In addition, selection and characterization of various phosphate mutants (with decresed or increased Pi level and acid phosphatases activity) - may provide information that help in elucidating Pi signaling pathway(s) and mechanisms of plant responses to Pi starvation.
