How plants adapt to nitrogen deficiency
Researchers at the University of Bonn discover gene variants in wheat and barley that improve nitrogen utilization
Wheat varieties with a specific NPF2.12 gene variant (right) - have significantly better root growth at low nitrogen levels in the soil than varieties without this gene variant (left). Nitrogen as a fertilizer can increase yields. However, too much nitrogen can also have negative effects, such as groundwater pollution, high energy consumption in fertilizer production and the generation of climate-relevant gases. Science is therefore looking for ways to help crops thrive with less nitrogen. Researchers at the University of Bonn have discovered gene variants of the nitrate sensor NPF2.12 that trigger a signal cascade chain at low soil nitrogen levels. This induces stronger root growth, resulting in improved nitrogen utilization. ...TO READ THIS ARTICLE, CREATE YOUR ACCOUNT
