Before leaf miner damage shows, horse chestnut leaves alter how they function

Researchers from Eötvös Loránd University (ELTE) and Semmelweis University have investigated what happens to horse chestnut leaves when they are attacked from within by the horse chestnut leaf miner. Their findings show that the functioning of the leaf changes while the damage is still barely visible to the naked eye. The results have been published in the journal Plant Stress.
