0引言硝态氮(NO3--N)是植物最重要的氮素来源之一。植物对NO3-的吸收和体内运转依赖细胞膜上的硝酸盐转运蛋白(NRT)，并在细胞膜质子泵(H+-ATPase)协助下执行主动运输过程。目前已在多个物种中鉴定出大量硝酸盐转运蛋白[1]，分别属于不同的亚家族，如NRT1(NPF),NRT2,CLC(氯离子通道蛋白)等[2]。部分NRT的生物学功能已得到验证，并在植物适应NO-胁迫过程中发挥重要作用[2-3]。越来3-胁迫过程中发挥重要作用[2-3]。越来越多的研究发现，植物硝酸盐转运蛋白不仅能够吸收、运转NO3-，而且在植物根系发育、离子运转以及逆境响应中发挥着重要作用[4]。此外，考虑到植物养分高效利用是建立在各营养离子互作的基础上，并与植物养分胁迫等非生物胁迫过程密切相关，因此单纯关注NRT在NO3-吸收运转方面的作用还不够，有在NO3-吸收运转方面的作用还不够，有必要进一步分析其在其他离子吸收运转中的调控作用，探寻植物离子...

INTRODUCTION Nitrogen (N) is a primary macronutrient for plants and a limiting factor in heterogeneous natural soils and agroecosystems. Since the nitrate supply in the soil is often insufficient to sustain optimal plant growth and development in agricultural production systems, farmers have to fertilize with large amounts of N to enable maximal crop yield, and the use of synthetic N has increased remarkably. However...

INTRODUCTION Nitrogen (N) is an essential element for plant growth and development. Plants absorb both inorganic and organic forms of nitrogen from the environment, but nitrate NO3(-) is the main form assimilated by most terrestrial plants (Nacry et al. 2013). The absorption of nitrate from the soil by higher plants is achieved through the combined activities of specific nitrate transporters (NRTs), encoded by member...
