Summary

Story summary

Penn State researchers studied corn's root adaptations during domestication for low nitrogen and drought resilience.
Key adaptations included fewer nodal roots and deeper root systems, shaped by increased carbon dioxide and irrigation over 9,000 years.
Findings could inform future corn breeding strategies for climate resilience.
The research was published in New Phytologist and involved multiple collaborating institutions.
