Abstract:
Taking Nicotiana tabacum as material，an over expressing MIR398 plasmid vector was constructed and introduced into the Nicotiana tabacum successfully.Some physiological indicators such as superoxide anion radical，malondialdehyde (MDA) and proline (Pro) content was studied and compared between wild type tabacum and transgenic plant T1 generation.The results showed that MDA and superoxide anion radical content accumulated more than wildtype plant，while Pro content was declined under the drought stress in the transgenic plant.This result further proved the role of miR398 in plant drought resistance.
