Phosphorus supply is a major factor responsible for reduced crop yields. As a result, plants utilize various adaptive mechanisms against phosphorus depletion, including lipid remodelling. Here we report the involvement of a novel plant lipid, glucuronosyldiacylglycerol, against phosphorus depletion. Lipidomic analysis of Arabidopsis plants cultured in phosphorus-depleted conditions revealed ind...

A gram-negative bacterium isolated from activated sludge was able to utilize up to 25 mM phosphonoacetate as the sole carbon and phosphorus source, with simultaneous excretion of virtually equimolar levels of phosphate. 2-Aminoethylphosphonate was similarly utilized with equivalent growth rates and cellular yields, while 3-aminopropyl-, 4-aminobutyl-, methyl-, ethyl-, and phenylphosphonates ser...

The synthesis and characterization of a novel class of highly-metallized, redox-active polyelectrolytes that employ phosphorus as a scaffold for the installation of transition metals is described. Pyrolysis of thin films of the title polyelectrolytes resulted in the production of magnetite crystallites and ill-defined carbon-, phosphorus- and oxygen-rich phases in char yields of nearly 50%.

this study was conducted during 2008-2009 to investigate the influence of different organic nutrient combinations on yields and quality of strawberry cv. kurdistan in iran. the experiment comprised of five organic nutrient treatment combinations including the recommended dose of n, p and k through chemical fertilizer as control. treatment n2 (manure+azotobacter+ woodash+phosphorus solubilizing ...

Stable crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reactionbetween hydantoins or thiohydantoins and dialkyl acetylenedicarboxylates in the presence oftriphenylphosphine. These phosphoranes undergo smooth intramolecular Wittig reaction followedby an electrocyclic ring opening to produce dialkyl (E)-2-(2,5-dihydro-5,5-diaryl-2-thioxo-1H-imidazol-4-yl)fum...

Silica supported phosphorus pentoxide (P2O5·SiO2) is an efficient catalyst for synthesis of 1,3,5-substituted pyrazoles via the condensation of 1,3-diketones and hydrazines. Simplicity of procedure, mild condition, being solvent-free, high yields, and easy workup are some advantages of this protocol.

Phosphorus pentoxide used on alumina (P2O5/Al2O3) as an inexpensive, eco-friendly and non-toxic acid catalyst for the one-pot synthesis of 1,8-dioxo-octahydroxanthenes via multi-component reactions under solvent-free conditions. The present approach offers several advantages such as short reaction times, high yields, easy purification, recovery and reusability of the catalyst.

The condensation of aromatic aldehydes, dimedone, ethylacetoacetate and ammonium acetate promoted by was Phosphorus pentoxide supported on alumina carried out under solvent-free conditions to afford corresponding polyhydroquinolinederivatives. This method provides several advantages including high yields, low reaction times, easy work up and little catalyst loading.
