The paperaim of the was to study the effect of low temperature stress on Avena nuda L. seedlings. Cold stress leads to many changes of physiological indices, such as membrane permeability, free proline content, malondialdehyde (MDA) content, and chlorophyll content. Cold stress also leads to changes of some protected enzymes such as peroxidase (POD),(More)
Oxidation of the thymine methyl group results in the formation of 5-(hydroxymethyl)uracil (HmU). HmU is a recognized endogenous DNA damage product, and HmU levels in DNA are increased by oxidant stress. Previous studies have reported substantially conflicting values for HmU levels in DNA. In studies utilizing postlabeling methods, HmU levels have been(More)
