Protein Biosynthesis in the Embryo and Endosperm during Embryogenesis in Pinus sylvestris L.

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.
