摘要: 氮是植物生长发育所必需的大量元素,参与植物体内各种代谢活动。硝态氮(NO3-)是植物可吸收利用的主要无机氮源。NO3-转运蛋白不仅介导植物正常生长发育过程中NO3-的吸收、转运和再利用,还参与调控植物对多种逆境的适应过程。结合最新报道,重点总结了近年来关于NO3-转运蛋白在植物适应低NO3-、低K+、盐、干旱及重金属镉等胁迫中的重要作用的研究进展,以期为今后进一步深入探究植物抗逆机理提供依据和参考。

Abstract: Nitrogen is an essential macronutrient for plants,and involved in various metabolic events. Nitrogen in nitrate(NO3-)is the major form of inorganic nitrogen source for plants. NO3-transporters not only play a vital role in nitrate uptake,transport and cyclic utilization during the whole growth and development of plants,but also participate in regulating the adversity adaptation in plants. In this review,we highlight recent progresses in studying the functions of NO3-transporters in the adaptation of plants to low NO3-,low K+,salt,drought and cadmium stresses,aiming at providing the reference for further exploring the stress resistance mechanisms in plants.

Key words: nitrogen, NO3- transporters, adversity adaptation
