Selenium modulates dynamics of antioxidative defence expression, photosynthetic attributes and secondary metabolites to mitigate chromium toxicity in Brassica juncea L. plants
Abstract
Abstract The study envisages the stress protective role of selenium (Se) against chromium (Cr) toxicity in Brassica juncea L. Plants were raised in pots with soils containing Cr (0 and 300 μMKg−1) and Se (0, 2, 4 and 6 μMKg−1) in binary combinations and harvested after 30 days of sowing. The harvested plant material was processed for several biochemical and molecular parameters. The observations made on significant results suggested that Se was able to protect the plants by restoring growth, reducing the oxidative damage (low levels of superoxide anions and hydrogen peroxide), and strengthened the enzymatic and non-enzymatic defence systems of B. juncea plants. Quantitative real time PCR studies on gene expression revealed that the expression of genes encoding the antioxidative enzymes (SOD, POD, CAT, GR and GST-1) was enhanced with Se application. Elevated contents of chlorophylls, carotenoids and gas exchange parameters also indicated that Se is instrumental in promoting photosynthetic efficiency, thereby ameliorating Cr toxicity. The expression of genes related to chlorophyll degradation also confirmed the observations. The contents of secondary metabolites (total phenols, flavonoids and anthocyanins) and the relative gene expression of phenylalanine ammonialyase and chalcone synthase, also showed enhanced levels in response to Se. The results thus indicated that Se application improves the overall physio-chemical characteristics of plants and helps them to overcome stress induced by Cr in the soil.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
