摘要：

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.
