摘要

The xerohalophyte Zygophyllum xanthoxylum efficiently compartmentalizes Na+ into vacuoles mediated by ZxNHX and maintains the stability of K+ in leaves to cope with saline and arid environments.However, the function of ZxNHX in controlling Na+ and K+ homeostasis at the whole-plant level remains unclear.Here, we investigated the role of ZxNHX in regulating the expression of genes involved in Na+ and K+ transport and spatial distribution in Z.xanthoxylum by using post-transcriptional gene silencing.The results showed that, 50 mM NaC1 induced an 620％ increase in transcripts of ZxSOS1 but only an 80％ increase in transcripts of ZxHKT1;1 in roots of wild-type (WT).Consequently, the transport ability of ZxSOS1 for Na+ exceeded that of ZxHKT1;1 and Na+ was loaded into the xylem by ZxSOS1 and delivered to the shoots.
