Compartmentation of metabolism within mitochondria and plastids

An important component of metabolic regulation is compartmentation and specialization. Subcellular compartmentation and the role of individual organelles is well studied, though less consideration has been given to the extent to which organelles differ between cells. Organelles extracted from whole tissue homogenates will have generally originated from a range of cell types. This review describes and assesses the regulation of metabolic activity in plants at both the cellular and subcellular level by considering specialization of mitochondria and plastids.
