Boron toxicity induces sulfate transporters at transcriptional level in Arabidopsis thaliana

Plants activate glutathione (GSH)-dependent detoxification pathways at biochemical and molecular levels under boron (B) toxicity. Sulfate uptake transport are necessary for GSH biosynthesis in plants. Therefore, the transcriptional regulation of some sulfate transporters was determined this study to clarify importance these leaf root tissues Arabidopsis thaliana toxic B conditions. The expression level SULTR1;3 dramatically increased moderate severe conditions, suggesting source-to-sink translocation Stable SULTR2;1, SULTR2;2, low SULTR3;5 might restrict movement into xylem leaves. SULTR3;1, SULTR3;2, SULTR3;3, SULTR3;4, SULTR4;1 SULTR4;2 were induced indicating an induction root-to-shoot translocation. These results showed that toxicity disrupt homogeneous distribution sulfur-containing compounds both A. thaliana. Moreover, we performed silico analysis microarray experiments determine common differentially expressed genes (DEGs) sulfur deficiency. Gene ontology, hierarchical clustering, coexpression network analyses DEGs demonstrated requirement A set involved metabolism coexpress with To best our knowledge, is first report focusing on
