A Mitochondrially Related Plastidial Transporter Regulates Photosynthesis in the Diatom Phaeodactylum tricornutum.

ABSTRACT: Eukaryotic phototrophs depend on the activity of two engines (the plastid and the mitochondrion) to generate the energy required for cellular metabolism. Because of their overlapping functions, both activities must be closely coordinated. At the plastid level, optimisation occurs through alternative electron transport, the diversion of excess electrons from the linear transport chain and metabolic exchanges. A similar process takes place in the mitochondria, with documented evidence of energy and redox equivalents being exchanged between the two organelles. Organelle-organelle energy interactions at the physiological level are well established in diatoms, an ecologically significant member of phytoplankton. Yet the molecular components involved in this process remain largely unknown. Here,
