“…In contrast, K + concentration displayed a gradually decreasing trend in lateral root with the increase of osmotic stress, but remained unchanged in other tissues (Figure 2b). Similar results were reported by Yue et al (2012), who found that osmotic stress significantly increases Na + concentration in leaf, whereas K + concentrations remained unchanged in all tissues. It was also suggested that the accumulation of larger quantities of Na + over K + in leaf may be used to osmotic adjustment in xerophytes H. ammodendron and Z. xanthoxylum (Wang et al 2004).…”

“…Our previous studies showed that Z. xanthoxylum absorbs Na + from low‐salt soils and accumulates Na + in leaves for osmotic adjustment ( Wang et al., ; Cai et al., ; Wu et al., ; Janz and Polle , ; Yuan et al., ). Further investigations revealed that Z. xanthoxylum becomes more tolerant to drought in the presence of moderate salinity with improved photosynthesis and water status ( Ma et al., ; Yue et al., ). Although the addition of 50 mM NaCl significantly increased the leaf Na + concentration in Z. xanthoxylum under drought stress, no significant change in K + concentration was observed ( Wu et al., ; Ma et al., ; Yue et al., ).…”

Zygophyllum xanthoxylum is a salt‐accumulating xerophytic species with excellent adaptability to adverse environments. Previous studies demonstrated that Z. xanthoxylum absorbs a great quantity of Na+ as an osmoregulatory substance under arid conditions. To investigate the nutritional status of Z. xanthoxylum in comparison with a typical glycophyte, Arabidopsis thaliana, seedlings were exposed to NaCl (50 mM for Z. xanthoxylum and 5 mM for A. thaliana), osmotic stress (–0.5 MPa), and osmotic stress combined with the NaCl treatment. Compared to the control, NaCl treatment or osmotic stress significantly increased Na+ concentration in leaves and roots of Z. xanthoxylum, but not of A. thaliana. Under osmotic stress, the addition of NaCl significantly increased Na+ concentration in leaves and roots of Z. xanthoxylum, resulting in improved biomass and tissue water content. However, such changes were not observed in A. thaliana. Compared to the control, K+ concentrations in leaves and roots remained unchanged in Z. xanthoxylum when exposed to osmotic stress, with or without additional 50 mM NaCl. In contrast, significant reductions in shoot K+ concentrations of A. thaliana were observed under osmotic stress alone or when combined with 5 mM NaCl. Moreover, NaCl alone or when combined with osmotic stress enhanced the accumulation of N, P, Fe, Si, Ca2+, and Mg2+ in Z. xanthoxylum, but did not cause such nutritional changes in A. thaliana. Compared to the glycophyte A. thaliana, Z. xanthoxylum could accumulate Na+ and maintain the stability of nutritional status at a relatively constant level to cope with drought stress.
