Figure 4. Growth of wild type and Sali3-2-transgenic seedlings cultured on Cd^{2 +}- or Cu^{2 +}-containing medium.

The seeds were sown on 1/2 MS agar plates adding different concentrations of CdCl₂ or CuCl₂. Seven days after sowing, the photographs were taken (A) and the root lengths were measured (B). S-1 and S-2: two different Sali3-2-transgenic lines. n = 30∼40. The error bars represent SD. **P<0.01 and *P<0.05.
