Özet
Aim of this work was to investigate effects of toxic levels of Cu, Zn and Fe treatments on small ubiquitinlike modifier (SUMO) machinery of Arabidopsis thaliana. SUMO is a 100-115 amino acid posttranslational modifier that can regulate stability, activity or sub-cellular localization of target proteins. A.thaliana plants were treated with 50 µM Cu, 700 µM Zn and 400 µM Fe for 7 d and then expressions ofgenes related to SUMOylation and deSUMOylation of target proteins were measured with qRT-PCR.Only Cu treatment was able to induce genes related to SUMOylation (SUM3, SAE2, SIZ1) of targetproteins, while all of the three metals used in this study was effective in inducing a deSUMOylationrelated gene. Results of this study indicate that deSUMOylation of proteins might be a part of plantresponse to metal toxicity.
