FIGURE 1.

Growth characteristics of hairy roots of PgTIP1-transformed soybean cotyledons under salt stress. (A-a,b) Culture of hairy roots of PgTIP1-transformed soybean cotyledons. (A-c) PCR verification, (A-d) changes in growth phenotype, (B) FW and DW, (C) maximal hairy root length, (D) contents of Na⁺ and K⁺, and (E) Na⁺/K⁺ ratio in the hairy roots under 80 mM NaCl treatment for 5 days. Each bar represents as means ± SD for each treatment (n = 3; or n = 10 for fresh weight or maximal length of hairy roots), means in bars followed by different letters show significant difference (P < 0.05) between the parameters of the empty vector-transformed and PgTIP1-transfromed soybean cotyledon hairy roots.
