H and Petrie (7) in 1927 described a generation of mitochondria in the scutellum of germinating corn (Zed mays). Part of these mitochondria appeared to be secreted from the scutellar epithelium into the endosperm, where they clustered about the starch granules, the granules subsequently undergoing a digestive erosion. Horning and Petrie believed the mitochondria to be the site of diastatic (glycosidic) enzyme syntheses. This hypothesis, however, is not in accord with modern cytological views that the mitochondria function as respiratory centers, and that protein (enzyme) synthesis occurs in the microsome fraction (2). It seemed desirable to clarify these divergent views by a study of Carbohydrases associated with isolated scutellum mitochondria.
