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...
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...
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...
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 ...
[56] claimed that Mg can be involved in the mitigation of metallic stress in plants by reducing the negative electrical potential, and thus, metal ion activities at the plasma membrane surface, or by enhancing the vacuolar sequestration of heavy metals via increasing H+-pumping activity in the ...
patterns in order to maintain growth under new conditions. Bacterial as well aseukaryotic cellssuch as yeast possess various response mechanisms to counterbalance fluctuations in growth parameters such as temperature, pH, solute concentration,oxygenation,metal ionconcentration, or high levels of organic ...
Monitor- ing using electrochemical characteristics of APM biofilms under metal ion stress is explored. In conclusion, effective engineering strategies can be proposed based on a deep understanding of the response mechanisms of APM to metal ion stress, which have been used to improve bioleaching ...
Osmolytes are small organic compounds produced by plants in response to abiotic stresses such as salinity, drought, heavy metals, and high temperature. The
For instance, the GO term “photosynthesis” was specifically enriched in ear tissue at the V12 stage and in tassel tissue at the R1 stage; the GO term “metal ion transport” was only enriched in tassel tissue at the V14 stage. Taken together, these preliminary results revealed the spatio...
