title: HAK transporters from Physcomitrella patens and Yarrowia lipolytica mediate sodium uptake.
abstract: The widespread presence of Na(+)-specific uptake systems across plants and fungi is a controversial topic. In this study, we identify two HAK genes, one in the moss Physcomitrella patens and the other in the yeast Yarrowia lipolytica, that encode Na(+)-specific transporters. Because HAK genes are numerous in plants and are duplicated in many fungi, our findings suggest that some HAK genes encode Na(+) transporters and that Na(+) might play physiological roles in plants and fungi more extensively than is currently thought.
