In the present review the role of ammonium component not connected with the synthesis of nitrogen-containing substances in plant cells is discussed.
In particular, it is devoted to the influence of NH4+ ions on the morphological changes of surface root cells, heterotrophic
CO2 fixation by cells, dark and light-dependent reduction of nitrate in plant cells, formation and functioning of cytoplasmic ribosomes in plant cells and
function of photosynthesizing organelle membrane systems. Our experimental data together with the results of the other researchers allow us to look at ammonium
participation in the life of plant cells more widely and not to consider NH4+ ions only as a substrate for ketoacids amination processes in
plant cells.
Key words: ammonium, effect, plant cells, functions of cells
