How plants rush energy to injured tissues to help them heal

A new study finds that plants respond to injury by actively redirecting sugars to damaged tissues, helping fuel the regeneration process. Using a fluorescent sensor to track sugar movement in living plants, researchers have discovered that wounds trigger a localized shift in energy transport, concentrating glucose around the injury site. The findings published in PNAS offer new insight into how plants coordinate repair and recovery and could help scientists better understand the mechanisms that support resilience in crops facing physical damage or environmental stress.
