Effect of enhanced UV-B radiation on DNA damage, repair and protein content in soybean hypocotyls
增强UV-B辐射对大豆胚轴DNA损伤、修复和蛋白质含量的影响

Ozone depletion in the upper atmosphere cause increasing doses of UV-B on the earth's surface and understanding how plants protect themselves against this exposure is important to maintain crop productivity. Soybean hypocotyls were treated with doses of UV-B at 8.22 kJ/(m~(2)d) and 12.42 kJ/(m~(2)d) UV-B radiation, corresponding to depletions in the stratospheric ozone of about 12 % and 20%, respectively, for a clear solstice day at Lanzhou city (36.04°N, 1550m),China.
