Popis:	Most of the higher plants growing in soils obtain their nitrogen in the form of nitrate. Control of the availability of intracellular nitrate has generally been considered to function via regulation of enzymes involved in nitrate assimilation. However, nitrate which can be accumulated in large quantities in certain crop plants, was shown to be mainly located in the vacuoles, and this vacuolar pool is probably a nitrogen reserve. The transfer processes for nitrate into the different compartments of the cells can thus be considered as limiting steps in nitrate assimilation.
