Nuts composition and effects

Leaf galls on Acer pseudoplatanus, caused by Eriophyes macrorrhynchus, were investigated in order to demonstrate suction marks in the nutritive tissue. After a special treatment that removed the cell content and the cell wall matrix, small holes with a diameter of approximately 0.35 μm were found in the cellulose skeleton of the cell walls. The holes originate by physical and enzymatical action of the stinging parasite.
