Subcellular phosphorus kinetics for Lake Ontario / by D.R.S. Lean and R.L. Cuhel. : En13-5/86-145E-PDF

"Radioactive phosphate has been used to show that during periods of high phosphate demand in Lake Ontario, all the soluble phosphate was taken up and replaced in a few minutes. The present investigation extends these observations to the subcellular level where the partitioning of recently assimilated phosphate into a low molecular weight fraction, phospholipids, ribonucleic acid (RNA), and polyphosphate and deoxyribonucleic acid (DNA) reflected the nutrient status of the plankton population. Furthermore, the rate of change in distribution of these fractions provided a measure of the rates of exchange between the subcellular compartments. The role of phosphate storage as polyphosphate was illustrated. Our results showed that the Lake Ontario plankton population was phosphorus deficient to some extent throughout the entire study period from April to November"--Management perspective.
