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
