New Regulatory Steps in Nitrate Assimilation of Lower and Higher Plants

  • R. Tischner
Conference paper


Nitrate is the major nitrogen source for most plants in the environment. However its availibility is low due to strong competition and to the low binding capacity to soil particles. Ammonium, the alternative nitrogen source, is bound by the cation exchange capacity of soils. However, major pH problems often arise from ammonium utilization by plants.
