Fig 8. The relative expresa sion levels of Ma4CL genes under NaCl treatment.

Ma4CL1 and Ma4CL3 expression in stems peaked at 1 h, Ma4CL2 and Ma4CL4 exhibited similar double-peaked expression patterns (a–d). In roots, Ma4CL1 and Ma4CL2 expression peaked at 6 and 3 h, respectively. However, the expression of Ma4CL3 and Ma4CL4 was down-regulated at 1 and 12 h (e–h). Error bars on each column indicate SDs from three replicates. Significant differences (p < 0.05) among treatment are marked with “*”.
