| Abstract: | Protein biosynthesis in the embryo and endosperm during embryogenesis in the Scots pine was studied using electrophoretic and immunochemical methods. Proteins of the albumin-globulin fraction were visualized already at the early embryonic stages. The major polypeptide components (48–60, 37–39, and 20–22 kDa) were gradually accumulated in the course of maturation. A high synchrony was noted between the stages of embryogenesis and molecular events related to protein biosynthesis and accumulation in the developing seed. |
