Enhancing Plant Growth and Response to Nitrogen

posted on 06/10/2011

Nitrogen is a vital nutrient for plant production. Scientists at the University of Missouri—St. Louis and the Donald Danforth Plant Science Center in St. Louis have determined a method to produce transgenic plants having the ability to increase the capture and utilization of nitrogen. Phospholipase D (PLD) and its lipid product phosphatic acid (PA) play important roles in a plant’s response to various stresses, such as root development, stomal development and freezing tolerance. By altering the expression (e.g., overexpressing or underexpressing) of phospholipase Dε (PLDε), plant growth and seed production are increased. By altering the expression of PLDε, this method increases plant yield, a plant’s biomass production, and the plant’s ability to grow under hyperosmotic stress such as drought.

Suggested Uses

  • Increase plant production without increasing the amount of fertilizer (e.g., nitrogen) used
  • Improve crop growth and yield under different levels of nitrogen

Advantages

  • 25% higher seed yield
  • 20% longer primary root length
  • Increase a plant’s ability to capture and utilize nitrogen (e.g. up to 40% greater use of nitrogen)
  • Increase plant’s biomass production: increase in leaf size and cell number
  • Increase plant growth under hyperosmotic stress
