Abstract: Nitrogen(N)is the largest demanded nutrient and its availability act as a major factor that limits the growth and development of plants. Imbalance nitrogen supply will lead lower production and excessive fertilization will cause environmental damage. Ammonium and nitrate is the main source of nitrogen absorption and utilization. This paper analyzed the research progress of the transport proteins that absorb NH+4 and NO-3, and the related genes expression, regulation and function in plants. We should strengthen the identification and understanding of the related genes of nitrogen uptake in trees, especially the pathway of nitrogen signal transduction, the mechanism of nitrate and ammonium transportation and regulation in plants, the interaction between proteins and components, the research about temporal and spatial expression patterns and regulation modes.
