Relative transcript levels of THI, RD22, NCED3 and SALT3 in transgenic hairy roots. Seven day-old composite transgenic plants were treated with 75 mM NaCl and the root samples were harvested for RNA extraction. Relative transcript levels of THI, RD22, NCED3 and SALT3 in 35S::NNC1m6 and RNAi-NNC1 transgenic roots compared to empty vector roots under normal and salt stress conditions. GmELF1b was used as the internal control. The data are the means ± SD of three replicates, and asterisks indicate a significant difference compared with the corresponding controls (*P < 0.05; **P < 0.01; ***P < 0.005)
