100 million years ago, long before human intervention, ancestors of grasses, including wheat, rice and maize, developed "bypasses" in chemical pathways used to create two critical compounds: lignin and starch. These more efficient pathways could explain why grass plants are so successful in nature and agriculture, according to a new paper published in Science on Aug. 20 by researchers from the University of Wisconsin–Madison and their collaborators.

Like a beltway that creates a more flexible traffic flow in a city, metabolic bypasses led to efficient and robust synthesis of both lignin and starch, chemical compounds that are…
