Abstract
Glycylsarcosine, a dipeptide which is resistant to peptidase activity, was accumulated intact against a concentration gradient by germinating embryos of Hordeum vulgare L., var. Maris Otter, Winter. This is the first clear evidence for the presence of a dipeptide transport system involved in the movement of protein reserves across the scutellum from the endosperm to the embryo during germination.
