The accumulation of oil in maturing safflower seeds was studied with an electron microscope. It was suggested that net-like clusters of proteinaceous particles in the cytoplasm are the site of triacylglycerol synthesis. No evidence was obtained to support the hypothesis that oleosomes originate in the, endoplasmic reticulum. A hypothesis has been proposed that triacylglycerols are initially synthesized by the net-like clusters in the cytoplasm to form a protein-oil complex, and the triacylglycerols are concentrated in the center of the cluster as their formation proceeds.
