  • Title: HAK transporters from Physcomitrella patens and Yarrowia lipolytica mediate sodium uptake.
    Author: Benito B, Garciadeblas B, Rodriguez-Navarro A.
    Journal: Plant Cell Physiol; 2012 Jun; 53(6):1117-23. PubMed ID: 22514087.
    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.
