Expression of some Genes in Response to Cadmium Stress in Triticum aestivum

Full Text PDF


Heavy metal toxicity has become a universal threat to all life forms, including plants. The main purpose of this study was to identify the gene expression profiling of MAPK, Thioredoxin, and MnSOD genes in wheat seedlings as affected by cadmium treatment. For this experiment, the quantitative Real-Time PCR on RNA isolated from shoots of wheat exposed to CdCl2 at a concentration of 100 mg/L was used. Results showed that in wheat seedling that exposed to cadmium stress for six days of beginning constant cadmium stress, Thioredoxin gene expression showed a large rise compared with the control sample, MnSOD gene expression increased compared with non-treated wheat seedling at the same times, but unlike the Thioredoxin and MnSOD genes, MAPK gene expression has no significant changes. Of course, it is possible that other times of beginning treatments (instead of six days) cause a change in this gene expression.
