Summary Metal ion homeostasis is regulated principally by metalloregulatory proteins that control metal ion uptake, storage and efflux genes. We have used transcriptional profiling to survey for genes that are rapidly induced by exposure to hi...
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...
Investigations were carried out on the relation between the martensite transformation and the stress induced by 3 MeV ion implantation in an austenite stainless steel (SS) sheet. Gold ions were implanted into the austenite SS sheet and the implantation dose was varied between 1 × 10 16/cm 2 ...
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...
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...
Metal ion transporters participate in maintaining the required levels of the various metal ions in the cellular compartments (Rolfs and Hediger, 1999). Breakdown of metal-ion homeostasis can lead to the metal binding to protein sites different to those designed for that purpose or replacement of ...
Named after the prototypical MerR regulator that induces gene expression in response to the presence of mercury ions, this family of transcription factors has been characterized in depth, particularly in the context of defense against heavy metal ions including copper, zinc, and lead (reviewed in ...
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
We carried out transcriptome analysis of tea plant leaves in response to three different Al levels (0, 1, 4 mM, for 7 days). In total, 794, 829 and 585 differentially expressed genes (DEGs) were obtained in 4 mM Al vs. 1 mM Al, 0 Al vs. 1 mM Al, and 4 mM Al vs. 0 Al ...
