FIGURE 5.

Expression patterns of genes with known roles in abiotic stress responses in tobacco plants. Gene expression levels in WT and sysr1-transgenic leaves (Lines 4 and 7) were compared by qRT-PCR after 0 and 1 h of treatment with 300 mM NaCl. Error bars indicate the standard deviation of three technical replicates, and the results were consistent in two biological replicates. EF1α was used as a reference gene. HPL, hydroperoxide lyase; DREB2A, dehydration-responsive element binding protein 2a; RD29B, responsive to desiccation 29; HSP17.6, heat shock protein 17.6.
