Model of Oilbody Biogenesis in Oleosin-Suppressed Lines.

The three major components of oilbodies are shown as phospholipids, oleosins (purple), and the TAG matrix (yellow).

(A) Biogenesis of an oilbody in a wild-type cell. The oleosin-saturated environment in ER results in production of lipid bodies completely covered by oleosins.

(B) Biogenesis of an oilbody in an oleosin-suppressed cell. Oilbodies that do not contain enough oleosins to coat their entire surface coalesce, forming larger lipid bodies. These particles might fuse until the surface is completely covered of oleosins.
