Nematodes invading European beech leaf tissue under electron microscope

Caption

A scanning electron microscope reveals nematodes (highlighted in green) inside the spongy mesophyll of a European beech (Fagus sylvatica) leaf infected with beech leaf disease (BLD). Eggs are marked in red for enhanced visualization. Natural fractures in the leaf surface suggest pathways for nematode migration from within the leaf to its outer surface. New research confirms that European beech is susceptible to BLD, raising concerns about global forest health.
