Localization of prolamin in oat scutellum cells before and after seed germination

Using fluorescent antibodies and high resolution light microscopy the reserve protein, prolamin (avenin) of oat scutellum was localized in the protein bodies of the scutellum cells of dry grain. But 1-3 days after seed germination, a large number of the protein bodies became devoid of prolamin indicating that the mobilization of prolamin in the scutellum of oat seeds after seed germination was very rapid.
