Identification and functional characterization of the chloride channel gene, GsCLC-c2 from wild soybean

Abstract

This study revealed that the expression of GsCLC-c2 is induced by NaCl-stress in the root of wild soybean. The tonoplast localized GsCLC-c2 transports Cl^- with a higher affinity than NO₃^- in a pH-independent fashion. GsCLC-c2 probably alleviates salt stress in planta through the sequestration of excess Cl^- into the vacuoles of root cells and thus preventing Cl^- from entering the shoots where it could result in cellular damages.
