摘要:

水稻是我国最重要的粮食作物,其产量的形成与养分的吸收密切相关。氮、磷、钾是植物最重要的三种营养元素,它们在根系的吸收和转运直接影响养分的利用效率。植物细胞膜质子泵能够将细胞质中的H+泵出细胞,在细胞膜内外形成H+浓度梯度,建立膜电位,并形成质子驱动力,从而为各种养分离子的跨膜运输提供动力。本文综述了近年来关于水稻根系细胞膜质子泵在铵态氮、磷酸盐和钾离子吸收中的作用机理,为水稻养分利用效率的提高提供理论依据。

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 membrane H+-ATPase of rice roots involved in the uptake of nitrogen, phosphate and potassium to provide more strategies for improving the nutrition use efficiency.

Key words: rice, nitrogen, phosphorus, potassium, PM H+-ATPase
