In an effort to investigate effects of environmental stressors on bacteria that are found to co-exist in several DOE-contaminated sites, we studied the effect of salt stress on Geobacter metallireducens strain GS15. A comparison of these results with salt stress in Desulfovibrio vulgaris and Shewan...
Osmolytes are small organic compounds produced by plants in response to abiotic stresses such as salinity, drought, heavy metals, and high temperature. The
4). DEGs in the green module, which were involved mainly in “transport” and “response to stimulus”, were generally upregulated after Ni treatment; DEGs in the blue module, which were involved mainly in “hormone signaling”, “oxidative stress”, “metal ion transport”, “channel ...
IRHO 7001 was enriched in several biological processes: (1) carbohydrate and amino acid metabolism related to membrane biosynthesis; (2) oxidative stress related to the regulation of transcription, defense response, and signal transduction; (3) transmembrane metal transport. Other essential processes en...
Several components of mucosal immunity are disrupted in CD. These include epithelial barrier integrity, mucous production and cell turnover, the production of antimicrobial peptides and proteins (AMPs), and the release of metal ion scavengers that contribute to nutritional immunity21,22,23. Nutritional...
Further, the OE plants exhibited low level of toxic metals, viz., Zn, Mn, Si and Cu, indicating a specific mechanism to cope with adverse growth conditions. These results suggest that CaFer1 might play an important role in maintaining metal ion homeostasis. The analysis of other Fe-...
2001). The availability of completedbacterial genomesequences has enabled us to search for the presence of additional types of MerR-like regulators. In this review, we describe the properties of some novel members of the MerR superfamily of transcription factors that do not require metal ions for...
Ten, seven, and nine MtMTPs responded to at least one metal ion treatment in the leaves, stems, and roots, respectively. Additionally, MtMTP1.1 , MtMTP1.2 , and MtMTP4 exhibited the highest expression responses in most heavy metal treatments. Our results presented a standpoint on the ...
When plants adapt to local environments, strong signatures of selection are expected in the genome, particularly in high-stress environments such as trace metal element enriched (metalliferous) soils. Using Arabidopsis halleri, a model species for metal
Disturbance of metal ions homeostasis and the detoxification response under cobalt stress Heavy metals such as Fe, Mn, Zn, Ni and Cu are essential nutrients for plants. Due to the low specificity of metal ion uptake and distribution systems in plants, the excess Co could be toxic by disturbing...
