Figure 3

Altered stress tolerance of the WRKY mutants. Seeds of wild type and mutants were grown on 1/2 MS media for four days and then were transferred to MS agar media without or with -0.75 MPa PEG, 200 mM mannitol or 150 mM NaCl. The picture was taken and the root length was determined at the 7th day after the transfer. The average root length of each genotype in MS medium and their standard errors were calculated from three independent experiments, every of each employed more than 25 seedlings per genotype. Relative root length was the ratio of average root lengths of seedlings in medium with 200 mM mannitol, -0.75 MPa PEG or 150 mM NaCl to those in MS medium. The standard errors were calculated from three independent experiments, every of each employed more than 25 seedlings per genotype. Groupings were based on Student-Newman-Keuls Test, a = 005.
