Abstract An investigation was made into the nature and extent of phosphorus and of nonhistone phosphorylated molecular species in histones and histone fractions. The distributions of radiophosphorus, of labeled nucleic acid precursors and of intact labeled nucleic acids during histone preparation and fractionation were presented.

Phosphorus in soils and plants – facing phosphorus scarcity
Plant and Soil, 2016Introduction Phosphorus is a fundamental nutrient for primary productivity of ecosystems and agricultural production, but its misuse impacts agricultural sustainability and has important environmental consequences. Access to global reserves of phosphate rock is politically sensitive and economically challenging.

Contribution of Particulate Phosphorus to Runoff Phosphorus Bioavailability
Journal of Environmental Quality, 2003ABSTRACTRunoff P associated with eroded soil is partly solubilized in receiving waters and contributes to eutrophication, but the significance of particulate phosphorus (PP) in the eutrophying P load is debatable. We assessed losses of bioavailable P fractions in field runoff from fine‐textured soils (Cryaquepts).

Quinquevalent phosphorus acids
2011This chapter shows the most important achievements in the area compounds containing three P–O bonds (phosphates), two P–O and one P–C bonds (phosphonates) as well as one P–O and two P–C bonds (phosphinates) in addition to the phosphoryl group P=O. Each of the main sections has been divided in the same way, covering synthesis, reactions and biological ...

Phosphorus Nitrides—the Cinderella of Phosphorus Chemistry?
Angewandte Chemie International Edition in English, 1992Stamped as long since discovered and therefore completely characterized, simple inorganic molecules like the phosphorus nitrides are often neglected. Yet although P3N5 was synthesized in 1903, its structure is still a mystery. W. Schnick et al. resurrected the chemistry of these compounds in the synthesis of P‐N analogues of known structural types.
