WSU News: Her greenhouse-grown soybean plants fix twice as much nitrogen from the atmosphere as their natural counterparts, grow larger and produce up to 36 percent more seeds. by Will Ferguson
'Tegeder designed a novel way to increase the flow of nitrogen, an essential nutrient, from specialized bacteria in soybean root nodules to the seed-producing organs. She and Amanda Carter, a biological sciences graduate student, found the increased rate of nitrogen transport kicked the plants into overdrive.
'Their work, published recently in Current Biology, is a major breakthrough in the science of improving crop yields. It could eventually help address society’s critical challenge of feeding a growing human population while protecting the environment.'
