Abstract:
Background
Plastid stromules are stroma-filled tubules that extend from the surface of plastids in higher plants and allow the exchange
of protein molecules between plastids. These structures are highly dynamic; stromules change both their shape and position
in the cytoplasm very rapidly. Previous studies with microfilament inhibitors indicated that stromule shape and movement are
dependent on the actin cytoskeleton. To learn more about the nature of the interactions of stromules and the cytoskeleton,
we imaged fluorescently-labeled microfilaments and plastids.
