In the two last decades, biochemical studies using mitochondrial swelling experiments or direct solute uptake in isolated mitochondria have lead to the identification of different transport systems at the level of the plant mitochondrial inner membrane. Although most of them have been found to have similar features to those identified in animal mitochondria, some differences have been observed between plant and animal transporters. More recently, molecular biology studies have revealed that most of the mitochondrial exchanges are performed by nuclear encoded proteins, which form a superfamily. Members of this family have been reported in animals, yeast as well as plants. This review attemps to give an overview of the present knowledge concerning the biochemical and molecular characterisation of plant members of the mitochondrial carrier family and, when possible, a comparison with carriers from other organisms.
