Induction of single-strand DNA breaks with synchrotron radiation in dry Barley nucleus
この論文をさがす
説明
Abstract Nuclei isolated from the embryos of dry seeds were exposed to synchrotron radiation (SR) from an electron storage ring (0.3 GeV). Dried nuclei were also gamma-irradiated for comparison. SR of broad wavelength above 115 nm increased the number of 3′-OH termini, which were produced from single-strand DNA breaks in the nucleus. The observed DNA damage is causally-related to the vacuum-u.v. component of SR.
