Mitochondria are crucial bioenergetic organelles for providing different metabolites, including ATP, to sustain cell growth both in animals and in plants. These organelles, delimited by two membranes (outer and inner mitochondrial membrane), maintain their function by an intensive communication with other organelles as well as with the cytosol. Transport of metabolites across the two membranes, but also that of inorganic ions, takes place through specific ion channels and transporters and plays a crucial role in ensuring an adequate ionic milieu within the mitochondria. In the present review we briefly summarize the current knowledge about plant mitochondrial ion channels and transporters in comparison to those of animal mitochondria and examine the possible molecular identity of the so far unidentified transport systems taking into account subcellular targeting predictions and data from literature.
线粒体是提供不同代谢物的重要生物能量细胞器，包括 ATP，以维持动物和植物细胞的生长。这些细胞器由两层膜（外膜和内膜）限定，通过与其他细胞器以及细胞质的密集通讯来维持其功能。代谢物穿过两层膜的运输，以及无机离子的运输，都是通过特定的离子通道和转运体进行的，这对于确保线粒体内部适当的离子环境至关重要。在本综述中，我们简要总结了目前关于植物线粒体离子通道和转运体的知识，与动物线粒体进行了比较，并根据亚细胞定位预测和文献数据，研究了迄今为止尚未确定的运输系统的可能分子身份。
