Future Prospects for the Identification of Nitrogen Signaling Components in Plants

  • Vieira Costa


The effect of nutrients on plant growth and development has been studied since the mid-sixteenth century. Since that time, evidence has mounted to support a model in which nitrate acts as a positive signal necessary for the induction of nitrate uptake and its reduction. Molecular-genetic studies in plants have also lent support for nitrate and its downstream metabolites to act as signaling molecules in higher plants.
