چکیده
Salt stress is an environmental that severely limits plant growth, development and productivity. The use of symbiotic relationships with beneficial microorganisms provides efficient, cost-effective environmentally friendly preventative method. growth-promoting rhizobacteria (PGPR) Rahnella aquatilis JZ-GX1 a moderately salinophilic strain good probiotic properties, although its ability to improve woody salt tolerance has not been reported. In this study, the effect on Cinnamomum camphora under different concentrations (0, 50 100 mM NaCl) was investigated reveal mechanism by which improves in C. camphora. results showed promoted growth root development. relative electrolyte leakage (REL) malondialdehyde (MDA) production inoculated plants were reduced 37.38% 21.90%, respectively, superoxide dismutase (SOD) activity leaves enhanced 321.57% NaCl treatment. It observed transmission electron microscopy concentration conditions, leaf cells significant reduction plasma membrane–cell wall separation intact chloroplast structures, tightly packed thylakoids. Importantly, inoculation Na+ accumulation K+ seedlings, these changes consistent upregulated expression channel SKOR vesicular membrane (Na+, K+)/H+ reverse cotransporter NHX1 roots. This study revealed enhancing

Surgical wound infection caused by Rahnella aquatilis.
Rahnella aquatilis is a water-residing gram-negative rod, a member of the family Enterobacteriaceae, isolated rarely from clinical specimens of immunocompromised patients. A case of a surgical wound infection caused by R. aquatilis in a patient who underwent a prosthetic surgical intervention is reported. The presence of inducible beta-lactamase was suggested by the disk induction test and the ...

Medicinal plants play a vital role for the development of new drugs. the bioactive extract should be standardized on the basis of active compound. the bioactive extract should undergo safety studies. Almost, 70% modern medicines in India are derived from natural products. Medicinal plants play a central role not only as traditional medicines but also as trade commodities, meeting the demand of ...
متن کاملRahnella aquatilis sepsis in an immunocompetent adult.
Rahnella aquatilis, a rare enteric gram-negative rod which is infrequently isolated in immunocompromised patients, was isolated as a causative organism of sepsis in a 26-year-old immunocompetent male patient. The contaminated intravenous fluid was confirmed to be the source of the organism.
متن کاملRahnella aquatilis Sepsis in a Premature Newborn
Rahnella aquatilis is an infrequently isolated Gram-negative rod within the Enterobacteriaceae family. The organism's natural habitat is water. The organism is rarely isolated from clinical specimens and it seldom causes infection in immunocompetent individuals. Here we present a one-month-old boy who was born prematurely at 27th week of gestation by cesarean section with a birth weight of 730 ...
متن کاملRegulation of ion homeostasis under salt stress.
When under salt stress, plants maintain a high concentration of K(+) and a low concentration of Na(+) in the cytosol. They do this by regulating the expression and activity of K(+) and Na(+) transporters and of H(+) pumps that generate the driving force for transport. Although salt-stress sensors remain elusive, some of the intermediary signaling components have been identified. Evidence sugges...
