Jul 10, 2023 · Nevertheless, the phosphite (Phi) form of P is widely present in various environments and participates in the global P redox cycle. Herein, global quantitative evidences of Phi are enumerated and the early origin and modern biotic/abiotic sources of Phi are elaborated.

Phosphite dehydrogenase catalyzes the NAD +-dependent oxidation of hydrogen phosphonate (common name phosphite) to phosphate in what amounts to a formal phosphoryl transfer reaction from hydride to hydroxide. This review places the enzyme in the context of phosphorus redox metabolism in nature and discusses the results of mechanistic ...

Jan 1, 2017 · Phosphite (HPO 3 2 −) is a highly soluble, reduced phosphorus compound that is often overlooked in biogeochemical analyses. Although the oxidation of phosphite to phosphate is a highly exergonic process (E o ' = −650 mV), phosphite is kinetically stable and can account for 10–30% of the total dissolved P in various environments. There is ...

Feb 1, 2015 · Effect of phosphite on the cell growth of C. reinhardtii using phosphorus-replete cells as inoculum. Phosphorus (P)-replete C. reinhardtii CC-125 cells (derived from an 8-day-old culture in TAP media) were inoculated in TA media supplemented with 1, 5, 10, 15 and 20 mM phosphite (Phi) as the sole P source.

The HP(O) 2 (OH) − species is called the hydrogenphosphite, and the HPO 3 2 −, the phosphite ion. (IUPAC recommendations are hydrogenphosphonate and phosphonate, respectively). H-Phosphonic acid is also used for preparing phosphite salts, such as potassium phosphite. 6.1.2 Reactivity of P–H Group6.1.2.1. Addition to Carbonyl Group and ...

Jan 1, 2022 · Phosphite [H 2 PO 3 − or HPO 3 2 (Phi)], an analog of phosphate [H 2 PO 4 − or HPO 4 −2 (Pi)], is gaining relevance as an inorganic biostimulant in agriculture, enhancing the growth, production, and productivity of various crop plants, while promoting better performance in species established in challenging environments. In nature, plants ...

Jun 1, 2005 · Phosphite dehydrogenase catalyzes the NAD +-dependent oxidation of hydrogen phosphonate (common name phosphite) to phosphate in what amounts to a formal phosphoryl transfer reaction from hydride to hydroxide. This review places the enzyme in the context of phosphorus redox metabolism in nature and discusses the results of mechanistic ...

Feb 1, 2021 · Phosphite (Phi) concentrations in soybean leaves, stems, and roots over a 48-h time course. Roots of 7-day-old soybean plants grown in a greenhouse were treated with 4.5 mg·mL −1 Phi. Leaves, stems, and roots were sampled at …
