초록

SOD2-transgenic T3 petunia line (A2-36-2-1-1-35) was treated with different levels of methyl viologen (MV) to determine its resistance to oxidative stress. Four (4) levels of MV (0, 100, 200, and 400 μM) were applied. The SOD2-transgenic T3 petunia line exhibited a very significant oxidative stress resistance at the highest MV concentration (400 μM) treatment compared to non-transgenic plant. RNA and protein expression of SOD2 transgene and higher parenchyma cell density in the transgenic petunias exhibiting resistance to oxidative stress proves its contribution to the expression of its resistance to oxidative stress.

Abstract

The SOD2-transgenic T3 petunia line exhibited a very significant oxidative stress resistance at the highest MV concentration (400 μM) treatment compared to non-transgenic plant. RNA and protein expression of SOD2 transgene and higher parenchyma cell density in the transgenic petunias exhibiting resistance to oxidative stress proves its contribution to the expression of its resistance to oxidative stress.
