Plastoglobule Formation and Organization Overview.

(A) Plastoglobules form exclusively on thylakoid membranes at areas of high curvature.

(B) Plastoglobules blister from the outer leaflet of the thylakoid membrane, and this half-lipid bilayer surrounds the plastoglobule. Mostly under oxidative stress conditions, the plastoglobules form interconnected linkage groups surrounded by a single continuous half-lipid bilayer.

(C) The half-lipid bilayer that surrounds the plastoglobule is studded with several proteins, both structural (plastoglobulins) and enzymatic (VTE1). These proteins would have their functional sites located within the plastoglobule interior.
