Project description:Verbena bonariensis is a species with excellent garden plant, good environmental adaptability and great potential for future development.Cadmium has caused serious heavy metal pollution in the soil, which has posed a great threat to plant growth. In this study, Illumina sequencing technology was used to sequence the transcriptome of Verbena bonariensis leaf under normal and Cd stress, respectively. In total, 95,013 transcripts and 63021 genes with an average length of 923 bp and 1,246 bp were constructed from the clean sequence reads, respectively. And 1037 DEGs were found in response to cadmium treatment, of which 10 were selected for qRT-PCR. In conclusion, this study first identified the Verbena bonariensis as a heavy metal tolerant plant and provided the first large-scale transcriptional data set in response to cadmium stress. Our research will help to understand the mechanism of resistance to Cd in the Verbena bonariensis and provide clues for further studies on the relationships between plants and heavy metals in other Verbenaceae plants.

Project description:Cupriavidus metallidurans CH34 is a metal resistant beta-proteobacterium. The genome of this bacterium contain many genes involved in heavy metal resistance. Gene expression of C. metallidurans was studied after the addition of of Zn(II), Cd(II), Cu(II), Ni(II), Pb(II), Hg(II) or Co(II). Keywords: Heavy metal stress response

Project description:We hypothesize that microarray-based analysis of Lycopersicon esculentum is a sensitive tool for the early detection of potential toxicity of heavy metals, as well as an effective tool for identifying the heavy metal-specific genes. To test the hypothesis, the Agilent whole-genome cDNA microarrays were used to assess the effects of heavy metal on L. esculentum at relatively low concentrations (1/10 LC50 of heavy metals). Results showed that the characteristic gene expression profiles induced by Cd, Cr, Hg and Pb were not only distinct from the control but also distinct from one another, demonstrating the feasibility of discriminating between the effects of these four heavy metals present at relatively low concentrations. Moreover, heavy metal-specific genes were identified by microarray analysis. These findings support the above hypothesis.

Project description:Xiangjiang River (Hunan, China) has been contaminated with heavy metal for several decades by surrounding factories. However, little is known about the influence of a gradient of heavy metal contamination on the diversity, structure of microbial functional gene in sediment. To deeply understand the impact of heavy metal contamination on microbial community, a comprehensive functional gene array (GeoChip 5.0) has been used to study the functional genes structure, composition, diversity and metabolic potential of microbial community from three heavy metal polluted sites of Xiangjiang River.

Project description:Three strains of the Aspergillus versicolor complex were isolated from a salty marsh at a former uranium mining site in Thuringia, Germany. The strains from a metal-rich environment were not only highly salt tolerant (up to 20% NaCl), but at the same time could sustain elevated Cs and Sr (both up to 100 mM) concentrations as well as other (heavy) metals present in the environment. During growth experiments when screening for differential cell morphology, the occurrence of guttation droplets was observed, specifically when elevated Sr concentrations of 25 mM were present in the media. To analyze the potential of metal tolerance being promoted by these excretions, proteomics and metabolomics of guttation droplets were performed. Indeed, proteins involved in up-regulated metabolic activities as well as in stress responses were identified. The metabolome verified the presence of amino sugars, glucose homeostasis regulating substance, (S)-abscisic acid and bioactive alkaloids, flavones and quinones.
