Fig. 2: Isolation and ultrastructure of citrus peel elaioplasts.

a Separation of elaioplasts on a discontinuous sucrose gradient (0.75, 0.92, 1.20, 1.50 M, Bands 1–4). b Light microscopy of purified elaioplasts. A representative micrograph of band 1 by density gradient contains a clean fraction of elaioplasts. Arrows indicate abundant colorless plastids with several sphere substructures clustering together. c An electron micrograph showing the ultrastructure of elaioplasts. The arrow indicates a plastoglobule
