title: [Influence of salicylic acid on biosynthesis of nucleic acids in Polyscias filicifolia cell culture under the action of unfavorable temperatures].
abstract: Amounts of DNA and RNA was increased (from 20 to 50%) in the presence of salicylic acid in cells of Polyscias filicifolia tissue culture grown in Murachige-Skoog modified medium. Treatment of the tissue culture with salicylic acid resulted in a significant increase of intracellular protein and decrease of proteolytic activity. In cells treated with salicylic acid, the amounts of DNA and RNA was higher in conditions of heat (3 h, 45 degrees C) and cold (24 h, 7 degrees C) stress in comparison with cells exposed to unfavorable temperatures without the initial treatment with salicylic acid.
