The synthesis of nucleic acids in cultivated Polyscias filicifolia cells exposed to oxidative stress

The synthesis of nucleic acids in cultivated Polyscias filicifolia cells exposed to oxidative stress The content of nucleic acids in the cell culture of fern-leaf aralia Polyscias filicifolia (Moore ex Fournter) Bailey (Araliaceae) exposed to heat shock (3 h at 45°C) decreased significantly (by 20–30%). The decrease in DNA and RNA contents was even larger (30–40%) after longer heat shock (24 h). Cold (24 h at 7°C) caused an even more dramatic decrease in DNA (by 34.2%) and total RNA (by 48%) contents. To judge from the DNA production rate, the presence of hydrogen peroxide and phenazine methosulfate in the culture exerted a dose-dependent and differently directed action on cell proliferation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

The content of nucleic acids in the cell culture of fern-leaf aralia Polyscias filicifolia (Moore ex Fournter) Bailey (Araliaceae) exposed to heat shock (3 h at 45°C) decreased significantly (by 20–30%). The decrease in DNA and RNA contents was even larger (30–40%) after longer heat shock (24 h). Cold (24 h at 7°C) caused an even more dramatic decrease in DNA (by 34.2%) and total RNA (by 48%) contents. To judge from the DNA production rate, the presence of hydrogen peroxide and phenazine methosulfate in the culture exerted a dose-dependent and differently directed action on cell proliferation.
