Project description:A1501 aroA is a gene derived from Pseudomonas stutzeri A1501, encoding a class II glyphosate-tolerant EPSP synthase. To understand the effect of class II EPSP synthase to E. coli under glyphosate shock, we constructed the class II EPSP synthase-expressing plasmid pUC-A1501. And pUC18 is the empty vector used as a control.

Project description:Petroleum is an important energy source. Due to its intensive exploration, accidents resulting in oil spills on soil are frequent, which creates consequences to ecosystems and human health. Rhizodegradation is an efficient technique that promotes the decontamination of polluted environments through the selection and use of rhizosphere microorganisms from phytoremediation plants. The aim of this study was to isolate, identify and characterize bacteria capable of degrading petroleum from the rhizosphere of Panicum aquaticum Poir., a plant that grows in petroleum contaminated soils. Three bacteria were isolated and characterized at the morphological (Gram staining), molecular (16S rRNA gene sequence analysis) and biochemical level. These bacteria were identified as new strains of Bacillus thurigiensis, Bacillus pumilus and Rhodococcus hoagii, which have been reported as potential bioremediators in the literature. All three bacteria were able to use petroleum hydrocarbons as the sole carbon source during in vitro degradation assays. Gas chromatography analysis of these assays indicated reductions of petroleum hydrocarbons between 23% and 96% within 48 h. Among the isolated bacteria, Rhodococcus hoagii presented the highest efficiency of petroleum consumption, reaching 87% of degradation after only 24 h of cultivation, which corresponds to a higher and faster degradation than previously reported, confirming the potential use of Rhodococcus hoagii for petroleum biodegradation.

Project description:Here, we report the draft genome sequences of Bacillus subtilis A1, Sphingobacterium sp. strain A3, and Pseudomonas sp. strain A29; Sphingobacterium sp. A3 and Pseudomonas sp. A29 were identified as Bacillus velezensis strain A3 and Bacillus subtilis strain A29, respectively, after a quality control check of the whole-genome sequences deposited in the NCBI database. These bacteria exhibit tremendous production of siderophores and significant antimicrobial potential. When inoculated on maize, these isolates increase its yield.

Project description:Background: Herbicides are environmental contaminants that have gained much attention due to the potential hazards they pose to human health. Glyphosate, the active ingredient in many commercial herbicides, is the most heavily applied herbicide worldwide. The recent rise in glyphosate application to corn and soy crops correlates positively with increased death rates due to Alzheimer's disease and other neurodegenerative disorders. Glyphosate has been shown to cross the blood-brain barrier in in vitro models, but has yet to be verified in vivo. Additionally, reports have shown that glyphosate exposure increases pro-inflammatory cytokines in blood plasma, particularly TNFα. Methods: Here, we examined whether glyphosate infiltrates the brain and elevates TNFα levels in 4-month-old C57BL/6J mice. Mice received either 125, 250, or 500 mg/kg/day of glyphosate, or a vehicle via oral gavage for 14 days. Urine, plasma, and brain samples were collected on the final day of dosing for analysis via UPLC-MS and ELISAs. Primary cortical neurons were derived from amyloidogenic APP/PS1 pups to evaluate in vitro changes in Aβ40-42 burden and cytotoxicity. RNA sequencing was performed on C57BL/6J brain samples to determine changes in the transcriptome. Results: Our analysis revealed that glyphosate infiltrated the brain in a dose-dependent manner and upregulated TNFα in both plasma and brain tissue post-exposure. Notably, glyphosate measures correlated positively with TNFα levels. Glyphosate exposure in APP/PS1 primary cortical neurons increases levels of soluble Aβ40-42 and cytotoxicity. RNAseq revealed over 200 differentially expressed genes in a dose-dependent manner and cell-type-specific deconvolution analysis showed enrichment of key biological processes in oligodendrocytes including myelination, axon ensheathment, glial cell development, and oligodendrocyte development. Conclusions: Collectively, these results show for the first time that glyphosate infiltrates the brain, elevates both the expression of TNFα and soluble Aβ, and disrupts the transcriptome in a dose-dependent manner, suggesting that exposure to this herbicide may have detrimental outcomes regarding the health of the general population.

Project description:Using whole genome microarray (Affymetrix ATH1) we studied the transcriptional response of Arabidopsis thaliana to glyphosate (Roundup Original) herbicde that inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) enzyme and thus disrupts aromaticamino acid biosynthesis. Few genes related to defense and secondary metabolism were altered. Experiment Overall Design: Surfactant (preference 0.25%) treated plants were used as carrier control group and EC50 concentration of glyphosate was used as the herbicide treatment group. Each of the control and treatment group consisted of 3 biological replicates and each biological replicates comprised leaves from 10 individual plants. RNA was extracted at 24h post treatment to study the transcriptional alterations caused by the herbicide treatment.

Project description:Although genetically modified glyphosate resistant soybeans with cp4-epsps gene have been widely planted all over the world, the proteomic characteristics of them are not very clear. In this study, the soybean seeds of a genetically modified (GM) soybean line H06-698 (H) with cp4-epsps gene and its non-transgenic counterpart Mengdou12 (M), which collected from different planting regions in two years, were analyzed with label-free proteomics technique.
