Changed patterns for different elements (A and B), ions content (C), fresh weight (D), and water content (E) under different salinity levels. A, typical freeze-substituted cross-sections and the typical element spectra of SEM-x-ray microanalysis from leaves of Thellungiella challenged with 0 (left) and 600 (right) mm NaCl; the positions of Na, Cl, and K in energy spectra are highlighted by arrows of different colors. The statistical results also are presented (supplemental Data S1). The relative contents of O, Na, Cl, K, and Ca in different leaves are shown (B). The Na⁺ and K⁺ contents were determined by means of flame emission, and the results are provided (C). After NaCl treatments, the shoot fresh weight and water content were decreased significantly (D).
