Cereals are the most broadly produced crops and represent the primary source of food worldwide.Nitrogen (N) is a critical mineral nutrient for plant growth and high yield, and the quality of cereal crops greatly depends on a suitable N supply.In the last decades, a massive use of N fertilizers has been achieved in the desire to have high yields of cereal crops, GINSENG ROYAL JELLY 2000MG leading to damaging effects for the environment, ecosystems, and human health.To ensure agricultural sustainability and the required food source, many attempts have been made towards developing cereal crops with a more effective nitrogen use efficiency (NUE).

NUE depends on N uptake, utilization, and lastly, combining Holders the capability to assimilate N into carbon skeletons and remobilize the N assimilated.The glutamine synthetase (GS)/glutamate synthase (GOGAT) cycle represents a crucial metabolic step of N assimilation, regulating crop yield.In this review, the physiological and genetic studies on GS and GOGAT of the main cereal crops will be examined, giving emphasis on their implications in NUE.
