Title | Storage of Quinolizidine Alkaloids in Epidermal Tissues ![]() | ||
Abstract | Epidermal cells of lupine leaves, petioles and stems are the main storage site for quinolizidine alkaloids with an alkaloid content of 5—6 mg/g fw (= 15 — 25 mmol/kg). Epidermal tissue also store malate and hydrogen ions and show a vacuolar pH of < 5. It is argued that the specific storage of alkaloids in the vacuoles of epidermal cells might be due to active transport via carrier proteins and cannot be explained by a simple diffusion and ion trap mechanism. | ||
