Low-Nitrogen Soil

MTU Scientists Get To The Root Of Poplar Tree Genes, Nutrient EfficiencyWorking to identify key genes in the root development of poplar trees, three Michigan Technological University scientists have come up with a new model for how genes interact and affect each other’s function. They also identified a network of genes that cause poplar roots to grow well in low-nitrogen soil, making them ideal candidates for biofuel tree plantations on marginal lands.
