Move over Arabidopsis, there’s a new model plant in town

Biological nitrogen fixation provides a free way for plants to alter and absorb the nutrient. Legumes like soybeans fix nitrogen due to the symbiosis with bacteria in the soil through development of nodules on their roots, but since grasses like corn and rice don’t form this specialized structures that relationship has been trickier to explore. Researchers have now shown the grass Setaria viridis received 100 percent of its nitrogen from the bacteria Azospirillum brasilense.
