Effect of short-term phosphate starvation on acid phosphatase activity of Carpinus pubescens and Eurycorymbus cavalerei

Effect of short-term phosphate starvation on acid phosphatase activity of Carpinus pubescens and... The objective of this research was to test the effect of phosphate starvation on the plant growth and acid phosphatase activity of Carpinus pubescens and Eurycorymbus cavalerei. Growth parameters of both trees with −P and +P exhibited little change. The Pi content in leaves of both Pi-free trees decreased to about 65–70% of the control after cultivation for two to three weeks. Root Pi content of both Pi deprivation trees were by 30–45% lower than that of the Pi supply. Phosphate starvation significantly increased both intracellular and extracellular acid phosphatase activities. Intracellular and extracellular acid phosphatase activities were negatively correlated with Pi content in roots, while intracellular acid phosphatase activities were significantly positively correlated with Pi content in leaves under Pi starvation. These results indicated that excreted acid phosphatase mainly released Pi from organic phosphorus compounds, while intracellular acid phosphatase in leaves regulated the redistribution of Pi in tissues for adaptation to a calcareous soil with a low phosphate level. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

The objective of this research was to test the effect of phosphate starvation on the plant growth and acid phosphatase activity of Carpinus pubescens and Eurycorymbus cavalerei. Growth parameters of both trees with −P and +P exhibited little change. The Pi content in leaves of both Pi-free trees decreased to about 65–70% of the control after cultivation for two to three weeks. Root Pi content of both Pi deprivation trees were by 30–45% lower than that of the Pi supply. Phosphate starvation significantly increased both intracellular and extracellular acid phosphatase activities. Intracellular and extracellular acid phosphatase activities were negatively correlated with Pi content in roots, while intracellular acid phosphatase activities were significantly positively correlated with Pi content in leaves under Pi starvation. These results indicated that excreted acid phosphatase mainly released Pi from organic phosphorus compounds, while intracellular acid phosphatase in leaves regulated the redistribution of Pi in tissues for adaptation to a calcareous soil with a low phosphate level.
