This review considers the evidence that ethylene biosynthesis is up-regulated by locally-generated signals in response to a change in external P supply, where the hormone then mediates, with auxin, changes in root system architecture. Subsequent changes in endogenous P evoke systemic responses whereby ethylene again is important in inducing some of the key signature changes observed in P-deprived tissues (eg. phosphate transporter and acid phosphatase up-regulation).
