Abstract
In chloronema cell suspension cultures of the Funaria hygrometrica, ammonium addition led to a rapid loss of nitrate reductase (NR) activity and a reduction in the levels of NR protein. The mRNA for NR was absent in ammonium-grown cells. Intracellular nitrate accumulation was also suppressed. Ammonium repression involving a transcriptional regulation has been proposed.
