Glycoprotein Synthesis in Plants: II. Structure of the Mannolipid Intermediate.

abstract：:Non-dormant and dormant seeds of Avena fatua metabolize (14)C-maltose in different ways: in non-dormant seeds, (14)C-maltose administered to the endosperm is readily converted to sucrose in the scutellum and translocated to the embryo; in dormant seeds, little sucrose is synthesized from (14)C-maltose, and maltose and...
