Project description:Pteris cretica L var. nervosa is one of the dominent fern species at antimony mining area where arbuscular mycorrhizal fungi can be found as a symbiosis. The effect of AMF on fern exposed to long-term excessive Sb was pooly understood. The project applied this fern co-cultivting with or withour AMF under different concentration of Sb in soil for charicterising Sb phytomediation ability of it along with the effect by AMF symbiosis.

Project description:In this study, blueberry transcriptomics and rhizosphere fungal diversity were analyzed by simulated potting method to treat blueberries with Cd stress, and the content of Fe, Mn, Cu, Zn and Cd in each tissue, soil and DGT of blueberries were determined. , Combined with transcriptomics for correlation analysis. A total of 84374 annotated genes were obtained in blueberry roots, stems, leaves and fruits, of which 3370 DEGs were found, and DEGs in the stem accounted for the highest proportion, totaling 2521. The annotation results show that these DEGs are mainly concentrated in a series of metabolic pathways related to signal transduction, defense and pathogenic response. Blueberries transfer excess Cd from the root to the stem for storage. The stem contains the highest Cd content, which is consistent with the transcriptomics analysis results, while the fruit contains the lowest Cd content. Correlation analysis between heavy metal content and transcriptomics results in each tissue was carried out, and a series of genes related to Cd regulation were screened. The blueberry root system relies on mycorrhiza to absorb nutrients in the soil. The intervention of Cd has severely affected the microflora structure of the blueberry rhizosphere soil. Coniochaetaceae, which is extremely tolerant, has gradually become the dominant population.

Project description:Comparison of probe-target dissociations of probe Eub338 and Gam42a with native RNA of P. putida, in vitro transcribed 16s rRNA of P. putida, in vitro transcribed 16S rRNA of a 2,4,6-trinitrotoluene contaminated soil and an uncontaminated soil sample. Functional ANOVA revealed no significant differences in the dissociation curves of probe Eub338 when hybridised to the different samples. On the opposite, the dissociation curve of probe Gam42a with native RNA of P. putida was significantly different than the dissociation curves obtained with in vitro transcribed 16S rRNA samples. Keywords: Microbial diversity, thermal dissociation analysis, CodeLink microarray

Project description:Phytoremediation soil polluted by heavy metal has been drawn on a worldwide attention from human society. However, how to improve the efficiency of plant remediation of soil contaminated by cadmium remains unknown. Previous studies showed that nitrogen (N) significantly enhanced cadmium uptake in poplar plants. In order to further explore the key role of N in the detoxification against cadmium stress in plants, this study try to investigate the poplar proteome and phosphoproteome difference between Cd stress and Cd+N treatment. In total, 5838 of the 6573 identified were quantified. With a fold-change threshold >1.3 and p-value<0.05, 375 and 108 proteins were up- and down-regulated by Cd stress when compared to the control, 42 and 89 proteins were up- and down-regulated, respectively, in Cd+N / Cd group, 522 and 127 proteins were up- and down-regulated, respectively, in Cd+N / CK group. In addition, the phosphoproteome data was obtained after the proteomic difference was normalized, and 1471phosphosites in 721 proteins were quantified. Based on a fold-change threshold >1.2, P-value <0.05, the Cd stress up-regulated 8 phosphosites in 8 proteins and down-regulated 69 phosphosites in 58 proteins, whereas N+Cd treatment up-regulated 95 phosphosites in 86 proteins and down-regulated 17 phosphosites in 17 proteins when compared to sole Cd stress. In addition, N+Cd treatment up-regulated 74 phosphosites in 60 proteins and down-regulated 42 phosphosites in 37 proteins when compared to the control.Several putative responses to stress proteins, transcriptional and translational regulation factors were up-regulated by addition ofexogenous nitrogen followed Cd stress at the proteome and phosphoproteome levels. Especially, heat shock protein 70 (HSP70), peroxidase (POD), zinc finger protein (ZFP), ABC transporter protein (ABC), eukaryotic translation initiation factor (elF) and splicing factor 3B subunit 1-like (SF3BI) were up-regulated by Cd+N treatment whether at the proteome or at the phosphoproteome levels, which was need to further study. In a word, taken together of proteome and phosphoproteome data, nitrogen serves a protective role in plants treated with Cd by multiple ways.
