ammonium assimilation occurs via glutamine synthetase EC 6.1.1.3 and enzyme, regardless of leaf age. L-glutamate is continuously synthesized and supplied to the phloem. Enzyme is localized to the phloem companion cells-sieve element complex in the leaf veins |

enzyme is active both in light and dark. In transgenic leaf disks expressing antisense enzyme mRNA, low level of enzyme limits the synthesis of glutamate. In the dark, low level of enzyme in transgenic leaves is not the main limiting factor of ammonium assimilation |
