Abstract
Phytoremediation has become a technology of choice for remediation of sites polluted with xenobiotics due to its low ecological impact, carbon sequestration, and lower cost. Plants have the natural ability to act as solar-powered pump-and-treat systems by taking up, metabolizing, or accumulating the xenobiotic. However, many of these detoxification mechanisms can lead to an up regulation of reactive oxygen species causing oxidative damage and/or morphogenic responses. In this study, we assess the tolerance of genetically engineered Arabidopsis thaliana plant lines to the two commonly found xenobiotics Trichloroethylene and Pyrene. These plants have been engineered to over-express the genes MIOX4, GlcUR, and GLOase in myo-inositol pathway leading to ascorbate (AsA) synthesis. The results of this study broaden our understanding of AsA's role in xenobiotic stress tolerance and highlight AsA's importance and positive effects for developing a more tolerant phytoremediation plant for xenobiotic clean up.
