Coincident with this development in chemical biology has been increased study and appreciation for the importance of ferrous iron during infection and more generally in host–pathogen interaction. Some of the recent findings are surprising and challenge long-standing assumptions about bacterial iron ...
was prepared by the method developed by WARING and WERKMAN (Arch. Biochem., 1942, v. 1, 303), treatment with 8-hydroxyquinoline and extraction of the metal complexes with chloroform at several pEL values; other.metallic ions and if desired, known amounts of iron, could then be added back...
Here we report for the first time that bacterial blight of rice can be alleviated by silicon (Si) added. In both inoculated and uninoculated plants, shoot dry weight was significantly higher in the +Si plants than in the −Si plants. A soil-cultured trial showed that disease severity was...
inorganic ion transport. Exchange of inorganic ions, such as iron, nitrate, and phosphate, are hallmarks of many well-characterized plant microbe symbioses19, and recent work from other labs has demonstrated links between nutrient status in plant roots and overall microbiome regulation20. To further ...
It is now understood that zinc is the second-most abundant trace metal in the human body after iron, and an essential component of protein structure and function. Importantly, zinc is a structural constituent of ∼750 zinc-finger transcription factors (2) enabling gene transcription, and is a...
The development of the “waste disposal hypothesis” of autoimmunity, which is related to complement deficiency, highlights the pivotal role of tingible body macrophages, particularly those present in the spleen. Macrophages play a central role in iron homeostasis, primarily in the spleen (red pulp)...
such as nitrogen fixation, mineral solubilization, phosphate and potassium absorption, siderophore production and iron sequestration ((Fig.1B; Table1) [28]. For example, inoculation of wheat seedlings withAzospirillum brasilense Sp245strain under drought stress significantly increased potassium (K), magn...
Arbuscular Mycorrhizal Fungi Alleviate the Negative Effects of Iron Oxide Nanoparticles on Bacterial Community in Rhizospheric Soils In our previous studies, such characteristics of AMF on plant growth were documented in response to metal engineered nanoparticle (ENP) treatments. However, the role of AMF...
A form of programmed cell death that is dependent on intracellular iron, characterized by the intracellular accumulation of lipid peroxides. Immune thrombocytopenia (ITP). An autoimmune disorder characterized by severe thrombocytopenia secondary to immune destruction of platelets that is responsible for incre...
women with a history of UTI seem to have an increased risk of recurrency within 3 to 4 months2. UPEC have the ability to cause symptomatic UTI by utilizing virulence factors such as type-1 fimbriae and P-fimbriae, capsule, lipopolysaccharides (LPS), α-hemolysin, iron acquisition systems, ...
