水稻根系细胞膜质子泵在氮磷钾养分吸收中的作用
Involvement of Plasma Membrane H +-ATPase in Uptake of Nitrogen, Phosphorus and Potassium by Rice Root
摘要
Abstract
Rice is an important staple crop in China.The yield of rice is closely related to the uptake of plant nutrients. As the major essential elements,nitrogen,phosphorus and potassium,their transport across the plasma membrane is critical for the nutrient absorption efficiency.The plasma membrane H +-ATPase actively drives H + outside the plant cells.Thus the proton gradient across the plasma membrane not only builds up the membrane potential but also forms the proton motive force for the transport of various nutrients.This review illustrates the mechanism of plasma mem-brane H +-ATPase of rice roots involved in the uptake of nitrogen,phosphate and potassium to provide more strategies for improving the nutrition use efficiency.关键词
