Abstract: | Data are raeviewed on mitochondrial systems whose functioning in plants diminishes the efficiency of oxidative phosphorylation. The involvement in this process of alternative oxidase, thermogenin-like uncoupling proteins, a 310 kD stress protein, free fatty acids, and the ADP/ATP antiporter is considered. The role of these systems is discussed with regard to thermogenesis, controlled production of reactive oxygen species, and regulation of bioenergetics and metabolism. |
