N2  - The structural organization of the cell walls at the aleurone-sub-aleurone junction has been examined by fluorescence microscopy in ungerminated seeds of two varieties of Hordeum vulgare L. (cultivars Himalaya and Vanier). The sub-aleurone cell walls that are immediately adjacent to the aleurone layer are considerably thicker than the remainder of endosperm walls and contain extensive deposits of aniline blue-positive material. The latter was not significantly affected by periodate oxidation and was removed from tissue sections only by &#946;-1,3-glucanases or hot dimethyl sulphoxide. These deposits may represent the primary substrate for endo-&#946;-1,3-glucanases secreted by the aleurone layer during germination.
