title: [Effect of external environmental factors on DNA content in Euglena].
abstract: The chromosome number and DNA content in Euglena gracilis cell have been shown by the number of investigators to vary essentially under the influence of some environmental factors (low phosphate and acetate concentrations, density of culture, temperature, light/dark regime, streptomycin treatment). Variability in the nuclear DNA quantity is supposed to be an important peculiarity of the structure and functional activity of the genome of Euglena gracilis.
