a Effect of NaCl (0, 100, 200 mM NaCl) on expression levels of GmNHXs in leaf (green), stem (brown) and root (dark brown) of soybean cultivars with contrasting salt tolerance nature G: Gujosoya-2 (sensitive), M: MAUS-47 (tolerant). Values are represented as mean ± standard error (n = 3). The DMRT at p ≤ 0.05 was applied. Treatments followed by the same lower-case letter for a particular genotype do not differ statistically. RQ: relative quantitative expression; b Heat map of the expression analysis of the identified GmNHXs in leaf, stem, and roots of the Gujosoya-2 (salt sensitive) and MAU-47 (salt tolerant) under saline conditions (0, 100 and 200 mM NaCl)
