Nitrogen-tracking tools for better crops and less pollution
Date:2/18/2014

Stanford, CA As every gardner knows, nitrogen is crucial for a plant's growth. But nitrogen absorption is inefficient. This means that on the scale of food crops, adding significant levels of nitrogen to the soil through fertilizer presents a number of problems, particularly river and groundwater pollution. As a result, finding a way to improve nitrogen uptake in agricultural products could improve yields and decrease risks to environmental and human health. Nitrogen is primarily taken up from the soil by the roots and assimilated by the plant to become part of DNA, proteins, and many other compounds. Uptake is controlled by a number of factors, including availability, demand, and the plant's energy status. But there is much about the transport proteins involved in the process that isn't understood. New work from Carnegie's Cheng-Hsun Ho and Wolf Frommer developed tools that could help scientists observe the nitrogen-uptake process in real time and could lead to developments that improve agriculture and the environment. It will be published by eLife on March 11 and is already available online.

Frommer had previously developed technology to spy on transport protein activity by using fluorescent tags in a cell's DNA to monitor the structural rearrangements that a transporter undergoes as it moves its target molecule. They tailored this technology to five nitrogen transport targets to monitor the nitrogen uptake and assimilation process. "We engineered these sensors to monitor the activity and regulation of suspected nitrogen transporters in living plant roots, which otherwise are impossible to study," Frommer said. "This suite of tools will vastly improve our understanding of the nitrogen-uptake process and will help to develop increased crop yields and decrease fertilizer-caused pollution."

Their method is applicable to any transporter from any organism, thereby enabling the otherwise exceptionally difficult analysis of trans
