Selenium Volatiles as Proxy to the Metabolic Pathways of Selenium in Genetically Modified Brassica juncea
Open accessAbstract
In this study we demonstrate that the headspace selenium volatiles could be used as proxy to the metabolic pathways in the Se-accumulator plant Brassica juncea. The selenium metabolic pathways in wild type plants are compared to those of several genetically modified cultures. Complementary use of atomic and molecular mass spectrometric techniques also allowed for identification of yet unreported minor headspace Se-containing volatiles such as CH3SeSeSeCH3, CH3SeSSeCH3, and CH3SeCH2CH3. By combining the information resulting from this research with the previously known information about selenium metabolism in B. juncea, it is possible that a more efficacious phytoremediation tool can be constructed.

The production of DMSe has been found in many environments, usually at higher rates than DMDSe, with exception of the production of DMDSe by Se-tolerant hyperaccumulator plants.

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.
