From: Cryo-electron tomography reveals four-membrane architecture of the Plasmodium apicoplast
Gaps between apicoplast membranes. A to C – Different sections of a reconstructed tomogram of a Plasmodium berghei merozoite. The apicoplast with its four membranes is located close to the nucleus. The plastid presents a widening between the two inner membranes and the two outer membranes (white arrowhead). A gap between the two outermost membranes is also occasionally observed (black arrow). In C, electron dense structures (white arrow) are present on some apicoplast membranes, possibly corresponding to protein complexes such as import apparatus. Scale bar = 50 nm.
