Ion concentration in WT and GmPIP1;6 overexpression plants in hydroponics condition. (A) and (B) The content of Na⁺ in roots and leaves. Ten-day-old WT and GmPIP1;6-Oe transgenic soybean plants were treated with or without 100 mM NaCl for 7 days. The roots or leaves of these seedlings were sampled for measurement. (C) Relative Na exclusion. Data are means of four biological replicates with error bars indicating SD. Asterisks indicate a significant difference between the WT and the transgenic lines (**P < 0.01). DW, dry weight.
