How plants compete for underground real estate affects climate change and food production

Dec. 9, 2020

In a paper published recently in Science, an international team of researchers led by Princeton graduate student Ciro Cabal sheds light on the underground life of plants. Their research used a combination of modeling and a greenhouse experiment to discover whether plants invest differently in root structures when planted alone versus when planted alongside a neighbor. “This study was a lot of fun because it combined several different kinds of mind candy to reconcile seemingly contradictory results in the literature: a clever experiment, a new method for observing root systems in intact soils and simple mathematical theory,” said Stephen Pacala, the Frederick D. Petrie Professor in EEB and the senior author on the paper.
