Figure 4From: Constitutive overexpression of soybean plasma membrane intrinsic protein GmPIP1;6 confers salt toleranceSalt stress tolerance of GmPIP1;6 overexpression transgenic lines. Ten-day-old WT and GmPIP1;6-Oe transgenic soybean plants were treated with or without 100 mM NaCl in nutrient solution for 7 days. (A) Photographs of WT and GmPIP1;6-Oe transgenic soybean plants with or without 100 mM NaCl treatment for 7 days. Bar = 3.5 cm. (B) SPAD of unifoliolate leaf in WT and GmPIP1;6-Oe with or without 100 mM NaCl treatment for 7 days. All data are means of four biological replicates with error bars indicating SD.Back to article page
