Mitochondria and chloroplasts have a prokaryotic origin, own DNA and generate ATP for the plant cell. The ion composition and concentration in these bioenergetic organelles impact on their physiology. Examples of documented affected processes are photosynthetic reactions, mitochondrial respiration and stress response. Electrophysiological and biochemical measurements strongly suggest the presence of ion channels and transporters in both mitochondrial and chloroplast membranes of higher plants. The development of model organisms and the availability of genetic tools in combination with cell and organism biology allowed to link specific genes to physiological functions. Genes from many different families (eg.,TPK, CLC, KEA and PHT4 in chloroplasts and GLR in mitochondria) have recently been shown to encode for organellar transport systems. For the Research Topic 'Ion transport in Chloroplast and Mitochondria Physiology in Green Organisms ', we welcome contributions discussing, proposing or investigating mechanisms of action, regulation and targeting for the already identified ion transport components. We also encourage potential contributors to unravel new players and possible interactions underlying the physiology of chloroplasts and mitochondria in plants and green organisms in general.
