This Project Grant award from the National Science Foundation (CFDA 47.074 - Biological Sciences) provides $640,474 to the University of California, Davis to develop tools and strategies for engineering plants with improved nitrogen use efficiency. The project aims to reprogram plant root growth and architecture to enhance the uptake and utilization of nitrogen fertilizers, thereby reducing the environmental impact and costs associated with excessive fertilizer application. Key activities include:

  • Employing synthetic optogenetic systems to remotely control belowground plant development by applying specific wavelengths of light to the plant canopy
  • Quantifying how an enhanced root system contributes to improved nitrogen uptake and use in tomato plants
  • Delivering programmed plants with novel approaches to regulate root growth in response to nitrogen availability
  • Making the new engineering tools developed through this project broadly available to the research community

This award reflects NSF's mission to advance scientific knowledge and address critical agricultural challenges related to sustainable nitrogen management. The project period runs from May 1, 2025 through April 30, 2028.
