Phosphorus transport and phosphorus nutrition in Lemna (Lemna major L.) and Spirodela (Spirodela oligorrhiza (Kurz.) Hegelm.)
Within 12 hours of transfer to a P-deficient medium Pi uptake rates by P-deficient (-P) plants were enhanced 30 to 120% compared with P-adequate (+P) controls when Pi was resupplied at 1 to 1000 ?M. The enhancement in Pi uptake rates with P-deficiency normally preceded and was more pronounced than other effects of P-deficiency such as reduced growth, reduced internal P concentration and appearance of visual symptoms.
