Phenotypic comparison of the growth of WT and T1 transgenic lines (L1, L7 and L8) overexpressing the SbSOS1 gene. (a-f) Germination of seeds from transgenic lines (L1, L7 and L8) and WT plants in (a) 0 mM, (b) 50 mM, (c) 100 mM, (d) 150 mM, (e) 200 mM, and (f) 300 mM NaCl. (g) The graph represents the per cent germination of transgenic lines (L1, L7 and L8) and WT plants in 0 mM, 50 mM, 100 mM, 150 mM, and 200 mM NaCl after 15 days. (h-j) Growth comparison of transgenic lines (L1, L7 and L8) and WT T₁ seedlings in (h) 0 mM, (i) 100 mM, and (j) 200 mM NaCl. (k-m) Growth of whole plants from transgenic lines (L1, L7 and L8) and WT plants at different NaCl concentrations: (k) 0 mM, (l) 100 mM and (m) 200 mM in hydroponic culture.
