Scientific Breakthrough Increases Plant Yields By One Third (wsu.edu)

Slashdot reader schwit1 writes, "Plant scientists have found a way to encourage plants to better use atmospheric nitrogen, thus increasing yields by more than one third. The technique not only produces healthier plants and more seeds, it reduces the need for fertilizer, the overuse of which can be an environmental issue." From WSU News: For years, scientists have tried to increase the rate of nitrogen [conversion] in legumes by altering...interactions that take place between the bacterioid and the root nodule cells. [Washington State University biologist Mechthild] Tegeder took a different approach: She increased the number of proteins that help move nitrogen from the rhizobia bacteria to the plant's leaves, seed-producing organs and other areas where it is needed. The additional transport proteins sped up the overall export of nitrogen from the root nodules.

This initiated a feedback loop that caused the rhizobia to start fixing more atmospheric nitrogen, which the plant then used to produce more seeds. "They are bigger, grow faster and generally look better than natural soybean plants," Tegeder said.

    Why didn't natural selection already "discover" this? Perhaps there's a big trade-off that hasn't been discovered yet.

    Honestly having enough food is the least of the problems with too many people on the planet.

    The big problem is that every calorie of food requires the input of 10 calories of fossil-fuel energy, mainly from oil and gas, which will be running out within your lifetime.
