Na＋ uptake pathways in the halophyte Suaeda maritime

摘要：

Reducing Na＋ influx must be the key step for controlling Na＋ accumulation compared with vacuolar Na＋ compartmentalization and Na＋ extrusion ( Apse et al., 1999 ; Ma et al., 2004 ;Martínez‐Atienza et al., 2007 ), neither of which would be sufficient alone.However, the pathways by which plants take up Na＋ are uncertain since Na＋ uptake by plant roots has largely been explored using species that accumulate little Na＋ into their leaves.By way of contrast, the halophyte Suaeda maritima accumulates, without injury, concentrations of the order of 400 mM NaCl in its leaves.Here we use S.maritima to examine Na＋ uptake pathways.
