The infectivity of sap expressed from the lower epidermis stripped from leaves systemically infected with potato virus Y , henbane mosaic virus or tobacco mosaic virus was compared with that of sap from the underlying mesophyll. Results suggested that the concentration of virus in each of the two tissues was about the same. Ultra‐violet irradiation of leaves infected with potato virus Y or henbane mosaic virus greatly reduced the infectivity of sap expressed from subepidermal tissues.
